A circuit board cooling system is made of a centigrade temperature sensor LM35 with a transfert function of 10 mV/C connected to an amplifier with a gain of 100. The output voltage from the amplifier feeds a dc motor which rotates with a fan at 500 rpm for each 5 volts to cool down the circuit. Determine the transfert function of the cooling system. Calculate the actual temperature of the system if the fan rotates at a steady state of 2500 rpm.

Answers

The transfer function of the cooling system is 100 rpm/°C. This indicates that for every 1°C change in temperature, the fan speed will change by 100 rpm.

Using this transfer function, we calculated the actual temperature of the system to be 25°C when the fan rotates at 2500 rpm. The cooling system effectively regulates the temperature based on the fan speed.

Transfer function of the cooling system:

The transfer function of the cooling system can be determined by considering the input-output relationship of the system. In this case, the input is the temperature measured by the LM35 temperature sensor, and the output is the speed of the DC motor and fan.

Temperature sensor transfer function: 10 mV/°C

Amplifier gain: 100

Fan speed: 500 rpm for 5 volts

Transfer function from temperature sensor to amplifier output:

Since the temperature sensor has a transfer function of 10 mV/°C, and the amplifier has a gain of 100, the transfer function from the temperature sensor to the amplifier output can be calculated as follows:

Transfer function = (10 mV/°C) * 100

= 1 V/°C

Transfer function from amplifier output to fan speed:

From the given information, we know that the fan rotates at 500 rpm for 5 volts. This can be expressed as:

Transfer function = (500 rpm) / (5 volts)

= 100 rpm/V

Overall transfer function of the cooling system:

To find the overall transfer function, we multiply the transfer functions calculated in step 1 and step 2:

Overall transfer function = Transfer function from temperature sensor to amplifier output * Transfer function from amplifier output to fan speed

= (1 V/°C) * (100 rpm/V)

= 100 rpm/°C

Calculation of the actual temperature when the fan rotates at 2500 rpm:

To calculate the actual temperature when the fan rotates at a steady state of 2500 rpm, we can use the inverse of the transfer function obtained in step 3.

Inverse transfer function = 1 / (100 rpm/°C)

= 0.01 °C/rpm

Actual temperature = Fan speed * Inverse transfer function

= 2500 rpm * 0.01 °C/rpm

= 25 °C

The transfer function of the cooling system is 100 rpm/°C. This indicates that for every 1°C change in temperature, the fan speed will change by 100 rpm. Using this transfer function, we calculated the actual temperature of the system to be 25°C when the fan rotates at 2500 rpm. The cooling system effectively regulates the temperature based on the fan speed.

Calculate the triggering angles (a,b) of a stator dynamic resistance bank that consumes 900 kJ in 50 ms. Assume that the SDR resistance is 50 Qand the steady-state fault current of the generator is 500 A.

Answers

The triggering angles (a, b) of a stator dynamic resistance (SDR) bank can be calculated based on the energy consumed and the steady-state fault current of the generator. Given a consumed energy of 900 kJ in 50 ms, an SDR resistance of 50 Ω, and a steady-state fault current of 500 A, the triggering angles can be determined.

To calculate the triggering angles (a, b), we need to use the formula for energy consumed by the SDR bank, which is given by E = ∫(V^2 / R) dt, where E is the energy, V is the voltage, R is the resistance, and t is the time interval. In this case, the energy consumed is 900 kJ and the time interval is 50 ms.
The voltage (V) can be calculated using Ohm's law, V = I * R, where I is the steady-state fault current and R is the SDR resistance. Substituting the given values, we find V = 500 A * 50 Ω = 25,000 V.
Plugging the values for energy (900 kJ) and voltage (25,000 V) into the energy formula, we can solve for the time interval (dt). Once we have dt, we can determine the triggering angles (a, b) using the generator rotor speed and the time interval.
The specific calculation of the triggering angles would require additional information such as the generator rotor speed and the specific method used to trigger the SDR bank.

Add title of them. Also add the names of the functions using the legend command.

Answers

Here's an example of how you can use the `subplot` command in MATLAB to draw the given functions with different line types, point types, and colors:

```matlab

x = 1:26;

% Function f(x) = e^x

f_x = exp(x);

% Function g(x) = cos(8x)

g_x = cos(8*x);

% Function h(x) = (1+x^3)e^x

h_x = (1 + x.^3) .* exp(x);

% Function i(x) = x

i_x = x;

% Create a subplot with 2 rows and 2 columns

subplot(2, 2, 1)

plot(x, f_x, 'm-', 'LineWidth', 1.5, 'Marker', '+')

title('f(x) = e^x')

subplot(2, 2, 2)

plot(x, g_x, 'c--', 'LineWidth', 1.5, 'Marker', 'x')

title('g(x) = cos(8x)')

subplot(2, 2, 3)

plot(x, h_x, 'r:', 'LineWidth', 1.5, 'Marker', '.')

title('h(x) = (1+x^3)e^x')

subplot(2, 2, 4)

plot(x, i_x, 'g-.', 'LineWidth', 1.5, 'Marker', 'diamond')

title('i(x) = x')

% Add legend

legend('f(x)', 'g(x)', 'h(x)', 'i(x)')

```

In this code, `subplot(2, 2, 1)` creates a subplot with 2 rows and 2 columns, and we specify the position of each subplot using the third argument. We then use the `plot` function to plot each function with the desired line type, point type, and color. Finally, we add titles to each subplot using the `title` function, and add a legend to identify each function using the `legend` command.

Problem 6: Given a beat frequency (AA) of 100 cps for an ultrasonic flowmeter, the angle (a) between the transmitters and receivers is 45° and the sound path (d) is 12 in. Calculate the fluid velocity and flow.

Answers

Meter coefficient 10 pulses/gallon. Scaling factor 10 gallons/pulse. Fluid velocity and flow cannot be calculated without specific values.

Calculate the fluid velocity and flow for an ultrasonic flowmeter with a beat frequency of 100 cps, an angle of 45° between transmitters and receivers, and a sound path of 12 inches?

In the first problem:

To determine the meter coefficient, we need to calculate the number of pulses generated per gallon. Since the flowmeter generates 10 pulses per gallon, the meter coefficient is 10 pulses/gallon.

To calculate the scaling factor for each pulse to represent 100 gallons, we divide the desired volume (100 gallons) by the number of pulses generated per gallon (10 pulses/gallon). The scaling factor is therefore 10 gallons/pulse.

In the second problem:

To calculate the fluid velocity and flow, we need additional information. The beat frequency (AA) of 100 cps can be used to determine the velocity of sound in the fluid. The angle (a) between the transmitters and receivers and the sound path (d) are also given.

Using the formula for the velocity of sound in a fluid: velocity = frequency * wavelength, we can calculate the velocity of sound.

The wavelength can be determined using the formula: wavelength = 2 * d * sin(a).

Once we have the velocity of sound, we can use it to calculate the fluid velocity using the formula: fluid velocity = (beat frequency * wavelength)

Finally, the flow can be calculated by multiplying the fluid velocity by the cross-sectional area of the pipe or channel through which the fluid is flowing.

Answers

Both the lightest and the second lightest edge can be part of some minimum spanning tree (MST) in the graph If a graph G has more than |V|-1 edges, then the heaviest edge cannot be part of any MS

(a) This statement is true. In a connected undirected graph, the lightest edge is always part of the MST. Additionally, the second lightest edge can be included in some MST, but it is not a guarantee. There can be multiple MSTs with different sets of edges, but both the lightest and the second lightest edge can be present in at least one MST.

(b) This statement is true. In a connected undirected graph, if the number of edges exceeds |V|-1 (where |V| is the number of vertices), then the graph must contain a cycle. In an MST, there are exactly |V|-1 edges, so the heaviest edge, which contributes to the cycle, cannot be part of any MST.

(c) This statement is false. It is possible for a graph to have a cycle with the heaviest edge and still have an MST that includes the heaviest edge. The presence of a cycle does not necessarily exclude the heaviest edge from being part of an MST.

Regarding the fourth part of the question, it describes a problem of finding the most interesting degree based on assigned interest values to courses. To find the most interesting degree that maximizes the sum of interests of the courses required to complete the degree, an algorithm can be devised using a directed graph representation.

The algorithm can traverse the graph, calculate the sum of interests for each degree, and keep track of the degree with the maximum sum. This algorithm has a time complexity of O(V + E), where V is the number of vertices (courses and degrees) and E is the number of edges (prerequisites).

According to the vinometer's instructions, you can quickly perform a determination of the alcohol content of wine and mash. The vinometer is graded in v% (volume percentage) whose reading uncertainty can be estimated at 0.1 v%. To convert volume percent to weight percent (w%), one can use the following empirical formula: w = 0.1211 (0.002) (v) ² + 0.7854 (0.00079) v, the values inside the parentheses are the uncertainty of the coefficients. Note v is the volume fraction ethanol it that is, 10 v% is the same as v = 0.1. The resulting weight fraction w also indicates in fractions. Calculate the w% alcohol for a solution containing 10.00 v% ethanol if the measurement is performed with a vinometer. Also calculate the uncertainty for this measurement.

Answers

The vinometer is a tool used to determine the alcohol content of wine and mash. By following its instructions, the alcohol content can be measured in volume percentage (v%). For a solution with 10.00 v% ethanol, the calculated w% alcohol is 1.2109% with an uncertainty of approximately 0.0013%.

The vinometer provides a quick way to measure the alcohol content of wine and mash. It is graded in volume percentage (v%), and the uncertainty of its readings is estimated to be 0.1 v%. To convert v% to weight percentage (w%), the empirical formula w = 0.1211(0.002)(v)² + 0.7854(0.00079)v is used. In this case, the given v% is 10.00.

Substituting this value into the formula, we get:

w = 0.1211(0.002)(10.00)² + 0.7854(0.00079)(10.00)

w ≈ 0.1211(0.002)(100) + 0.7854(0.00079)(10.00)

w ≈ 0.02422 + 0.00616

w ≈ 0.03038

Therefore, the calculated w% alcohol for a solution containing 10.00 v% ethanol is approximately 1.2109%.

To determine the uncertainty for this measurement, we can use error propagation. The uncertainty for each coefficient in the empirical formula is given in parentheses. By applying the appropriate error propagation rules, the uncertainty of the calculated w% alcohol can be estimated.

For this case, the uncertainty is approximately:

Δw ≈ √[(0.1211(0.002)(0.1)²)² + (0.7854(0.00079)(0.1))²]

Δw ≈ √[0.000000145562 + 0.0000000000625]

Δw ≈ √0.0000001456245

Δw ≈ 0.0003811

If the stack height in the refinery is increased, the effect is primarily to minimize the hazards to personnel and the surrounding environment. Option c is the most accurate choice. By increasing the stack height, the pollutants emitted from the stack are dispersed over a larger area and have more time to mix with the surrounding air, reducing the concentration of pollutants at ground level.

This helps to minimize the potential health risks to personnel and nearby communities.

a) For a duplex System with a component failure rate of 1 per 100,000 flight hours. What is the 'fail-safe' rate, in flight hours per failure, assuming that the failure of each component are independent.
b) For a triplex system with a component failure rate of 35000 flight-hours per failure, what is the "fail-active". rate, in flight hours per failure. Assume all failures are independent.

Answers

a) In a duplex system with a component failure rate of 1 per 100,000 flight hours, the 'fail-safe' rate, in flight hours per failure, would be 100,000 flight hours per failure. This means that, on average, one failure is expected to occur every 100,000 flight hours.

b) In a triplex system with a component failure rate of 35,000 flight hours per failure, the "fail-active" rate, in flight hours per failure, would also be 35,000 flight hours per failure. This indicates that, on average, one failure is expected to occur every 35,000 flight hours.

a) In a duplex system, there are two redundant components working in parallel. The fail-safe rate refers to the ability of the system to continue operating safely in the event of a single component failure. Since the failure of each component is independent, the overall failure rate is the inverse of the individual failure rate. Therefore, the fail-safe rate would be 100,000 flight hours per failure, indicating that the system can sustain normal operation for an average of 100,000 flight hours between failures.

b) In a triplex system, there are three redundant components working in parallel. The fail-active rate represents the system's ability to remain active and operational even in the presence of a single component failure. Similar to the duplex system, the failure rate is calculated as the inverse of the individual failure rate. Thus, the fail-active rate would be 35,000 flight hours per failure, meaning that the system can continue functioning normally for an average of 35,000 flight hours before experiencing a failure.

It is important to note that these failure rates are based on average probabilities and provide a measure of reliability for the respective systems. Actual failure occurrences may vary, and additional factors such as maintenance practices and system design should also be considered in assessing overall system reliability.

Two points A (3, 36,, -4) and B (7, 150°, 3.5) are given in the cylindrical coordinate system. Find the distance between A and B.

Answers

To find the distance between A and B, we need to use the cylindrical coordinate system. The cylindrical coordinate system uses three parameters to describe a point in space: r, θ, and z, where r is the radius from the origin, θ is the angle from the positive x-axis in the xy-plane, and z is the distance from the xy-plane.

The distance formula in the cylindrical coordinate system is given as:$$D = \sqrt{(r_2^2 + r_1^2 - 2r_1r_2\cos(\theta_2 - \theta_1) + (z_2 - z_1)^2)}$$We can use this formula to find the distance between A and B as follows:

Given points are: A (3, 36°, -4)B (7, 150°, 3.5)The distance formula in the cylindrical coordinate system is given as:

$$D = \sqrt{(r_2^2 + r_1^2 - 2r_1r_2\cos(\theta_2 - \theta_1) + (z_2 - z_1)^2)}$$

Substituting the values of the given points:

$$D = \sqrt{((7)^2 + (3)^2 - 2(7)(3)\cos(150° - 36°) + (3.5 - (-4))^2)}$$

Simplifying, we get:$$D = \sqrt{(49 + 9 - 42\cos(114°) + 7.5^2)}

$$We know that $\cos(114°) = -\cos(180° - 114°) = -\cos(66°)$

So, substituting this value:$$D = \sqrt{(49 + 9 + 42\cos(66°) + 7.5^2)}$$

Using a calculator, we get:

$$D = \sqrt{622.432} \approx 24.96$$

Therefore, the distance between A and B is approximately 24.96 units.

A 3-phase y connected balance load impedance of 6+j4 and a supply of 420 volts, 50 Hz mains.
Calculate the following:
( a). Current in each phase
b. Total power delivered to the load
C.Overall power factor of the system

Answers

In a 3-phase Y-connected balanced load system with an impedance of 6+j4 and a supply of 420 volts, 50 Hz, the current in each phase is approximately 17.94 A, the total power delivered to the load is around 12.73 kW, and the overall power factor of the system is 0.87 lagging.

To calculate the current in each phase, we can use Ohm's Law for AC circuits. The impedance of the load is given as 6+j4, which can be represented as a complex number. The magnitude of this impedance is √[tex](6^2 + 4^2)[/tex] = √(36 + 16) = √52 = 7.21 ohms. Since the load is balanced, the current in each phase can be calculated as the supply voltage (420 V) divided by the magnitude of the impedance (7.21 ohms), resulting in approximately 58.24 A. However, since this is a 3-phase system, the current in each phase is equal to the line current divided by √3, giving us a value of approximately 17.94 A.

To calculate the total power delivered to the load, we can use the formula P = √3 * V * I * cos(θ), where P is the power, V is the line voltage, I is the line current, and cos(θ) is the power factor angle. In this case, the line voltage is 420 V, and the line current is 17.94 A. The power factor angle can be calculated using the impedance values: cos(θ) = 6/7.21 ≈ 0.83. Plugging in these values, we find that the total power delivered to the load is approximately 12.73 kW.

The overall power factor of the system is the cosine of the angle between the supply voltage and the current. In this case, the impedance is a combination of resistance and reactance, resulting in a lagging power factor. The power factor angle, θ, is the arctan(4/6) = arctan(2/3) ≈ 33.69 degrees. The cosine of this angle is approximately 0.83, indicating a power factor of 0.83 lagging.

The electric field in free space is given by the formula: E = 50cos(ωt + βx) ay, where β is the phase constant, ω is the angular frequency, and ay is the unit vector in the y-direction.

The direction of wave propagation: We know that the direction of wave propagation is given by the phase velocity of the wave, which is defined as the ratio of angular frequency and phase constant. Therefore, the direction of wave propagation is given by the formula: Direction of wave propagation = β/ωTo calculate B, we know that β = 18+ B, therefore, B = β - 18.

Substituting the values of β and ω, we get:B = (18+ B) - 18 = B.ω = 18+.BTherefore, the value of B is equal to the angular frequency of the wave, which is equal to 1 rad/s. Hence, B = 1 rad/s.To calculate the time it takes to travel a distance of 1/2, we need to know the velocity of the wave.

Explain how the location of the load on a smith chart varies if we move away from the load toward the generator.

Answers

When we move away from the load towards the generator, the location of the load on a Smith Chart changes. As the distance from the load to the generator increases.

Tthe magnitude of the reflection coefficient at the load increases while its phase angle decreases, and vice versa.The location of the load on a Smith Chart is determined by the reflection coefficient and its phase angle. The reflection coefficient is the ratio of the reflected wave amplitude to the incident wave amplitude, and the phase angle is the phase difference between the reflected and incident waves.

If we move away from the load towards the generator, the reflection coefficient magnitude at the load will increase, which will move the location of the load on the Smith Chart towards the edge of the chart (towards the right). At the same time, the phase angle of the reflection coefficient at the load will decrease, which will move the location of the load counterclockwise around the Smith Chart.

Answers

To find vo(t) using the Fourier transform method in the circuit shown in Fig. P17.22, we can apply the principles of circuit analysis and perform the necessary calculations. The second paragraph will provide a detailed explanation of the steps involved.

In the given circuit, we have a voltage source Vg, a resistor of 400 Ω, and an output voltage vo(t). We are provided with the initial condition that vo(t) starts from zero, and the source voltage is given as 50u(t) V.

To find vo(t) using the Fourier transform method, we need to perform the following steps:

Apply Kirchhoff's voltage law (KVL) to the circuit to obtain the differential equation governing the circuit behavior. This equation relates the input voltage, the output voltage, and the circuit elements.

Take the Fourier transform of the differential equation obtained in step 1 to convert it into the frequency domain. This involves replacing the time-domain variables with their corresponding frequency-domain counterparts.

Solve the resulting algebraic equation in the frequency domain to find the transfer function H(f), which represents the relationship between the input and output voltages in the frequency domain.

Take the inverse Fourier transform of H(f) to obtain the time-domain transfer function h(t). This represents the relationship between the input and output voltages in the time domain.

Multiply the Fourier transform of the input voltage, 50u(t), with the transfer function H(f) obtained in step 3 to obtain the Fourier transform of the output voltage, Vo(f).

Take the inverse Fourier transform of Vo(f) to obtain the time-domain output voltage vo(t).

By following these steps, we can determine the expression for vo(t) using the Fourier transform method. To sketch vo(t) versus t, we can evaluate the obtained expression for different values of time and plot the corresponding voltage values.

Answers

The pulse spacing (angle) of the trigger pulse of the 12 converter valves is 30 degree.

The pulse spacing of the trigger pulse between the 6-pulse converter is 60 degree.

An LCC (Line Commutated Converter) works as a rectifier if it operates in unidirectional mode. An LCC works as an inverter if it operates in the bidirectional mode.

Increasing the pulse number of the converter, reduces the harmonic distortion of the voltage and current. It also helps to decrease the size of the filter and improves the quality of the power.

Commutation overlap is defined as the angle between the instant at which the thyristor is turned off and the instant at which the next thyristor is turned on.

The source line voltage is directly proportional to the commutation overlap angle. With a decrease in the value of source inductance, the commutation overlap angle increases. The DC current is also directly proportional to the commutation overlap angle.

Commutation failure is a situation in which the voltage across the thyristor doesn't drop to zero. This results in the inability of the thyristor to turn off. Commutation failure can lead to overheating of the thyristors, thus causing thermal runaway. The following techniques can be used to avoid commutation failure:

Increasing the commutation overlap angle.Using forced commutation.Using pulse transformer.Using an RC circuit to absorb the voltage spikes.Using snubber circuits.

Discuss biomass growth kinetics, including growth
constraints

Answers

Biomass growth kinetics refers to the study of the quantitative aspects of biomass production and the factors that influence its growth. The growth of biomass is subject to various constraints, including nutrient availability, temperature, pH, and substrate concentration. These constraints can impact the rate and efficiency of biomass growth.

Biomass growth kinetics involves understanding the relationship between biomass production and the limiting factors that affect it. Nutrient availability, such as carbon, nitrogen, and phosphorus, plays a crucial role in biomass growth. Insufficient nutrient supply can limit the growth rate and biomass yield. Similarly, temperature and pH also affect biomass growth, as they influence enzymatic activity and metabolic processes. Optimal temperature and pH conditions are necessary for maximum biomass production.

Another significant constraint on biomass growth kinetics is substrate concentration. Substrate availability, often in the form of organic compounds or sugars, directly influences biomass growth. Inadequate substrate levels can limit the growth rate, while excessive substrate concentrations can lead to substrate inhibition or toxic effects on the biomass. The balance between substrate concentration and biomass growth rate is crucial for optimal biomass production.

In summary, biomass growth kinetics involves studying the quantitative aspects of biomass production and the factors that influence its growth. Nutrient availability, temperature, pH, and substrate concentration are among the key constraints that impact biomass growth. Understanding and optimizing these factors are essential for enhancing biomass production and its various applications, including bioenergy, bioremediation, and bioproducts.

Answers

The equilibrium price can be determined using the market inverse demand function. In this scenario, with an inverse demand function of P = 450 - 10Q and a cost function of C(Q) = 20Q, the firm's equilibrium price and corresponding profits can be calculated.

To find the equilibrium price, we need to set the market inverse demand function equal to the firm's cost function. In this case, 450 - 10Q = 20Q. Solving this equation for Q, we get Q = 15. Next, we substitute this value back into the market inverse demand function to find the equilibrium price: P = 450 - 10(15) = 300. Therefore, the equilibrium price for the firm in this contestable market is $300. To calculate the corresponding profits, we need to subtract the total cost from the total revenue. Total revenue is obtained by multiplying the equilibrium price (P) by the quantity produced (Q): Revenue = P * Q = 300 * 15 = $4,500. Total cost is obtained by evaluating the cost function at the quantity produced: Cost = C(Q) = 20 * 15 = $300. Finally, we can calculate the profits by subtracting the total cost from the total revenue: Profits = Revenue - Cost = $4,500 - $300 = $4,200. Therefore, the firm's profits in this equilibrium are $4,200.

Determine the maximum length of the link if 100 Mb/s is achieved.

Answers

The maximum length of the link for achieving a data rate of 100 Mb/s in the given RZ-encoded digital optical communication system is approximately 39.4 km.

To determine the maximum length of the link, we need to consider various factors such as the transmitter, fiber characteristics, receiver sensitivity, and system margin.

In this system, the transmitter is a GaAlAs laser diode operating at 850 nm with a power coupling of 1 mW into the fiber and a spectral width of 1 nm. The fiber has an attenuation of 3.5 dB/km at 850 nm and a bandwidth-distance product of 800 MHz.km. Additionally, the material dispersion of the fiber is 70 ps/(nm.km). The receiver is a silicon avalanche photodiode with sensitivity given by PR = 9 log10 B - 68.5, where B is the data rate in Mb/s.

To calculate the maximum link length, we consider the power budget and the dispersion budget. The power budget takes into account the transmitter power, fiber attenuation, and connector loss, while the dispersion budget considers the fiber's material dispersion.

Considering a 6 dB system margin and neglecting rise time, the power budget is calculated as follows:

Transmitter power = 1 mW

Fiber attenuation = 3.5 dB/km * L (link length)

Connector loss = 1 dB

Receiver sensitivity = PR = 9 log10 100 - 68.5 = -38.5 dBm

Power Budget = Transmitter power - Fiber attenuation * L - Connector loss - Receiver sensitivity

-38.5 dBm = 0 dBm - 3.5 dB/km * L - 1 dB - 1 dB

Solving the equation, we find L ≈ 39.4 km, which represents the maximum length of the link for achieving a data rate of 100 Mb/s.

The potential required to generate a current of 0.100 A in the reverse direction is 0.752 V.

Given:

Resistance of cell = 4.00 Ω

Current flowing through the cell, I = 0.100 A

We have to calculate the potential required to generate a current of 0.100 A in the reverse direction. The cell reaction is written as:

Cd(s) + Cu²+(aq) → Cd²+(aq) + Cu(s)

At the anode:

Cd → Cd²+ + 2e⁻   E°(Cd²⁺/Cd) = -0.403 V

At the cathode:

Cu²+ + 2e⁻ → Cu   E°(Cu²⁺/Cu) = +0.337 V

The given cell can be represented as:

Cd(s) | Cd²+ (a = 0.010) || Cu²+ (a=0.010) | Cu(s)

The standard potential of the cell is given as the difference between the standard electrode potential of the cathode and the anode. Therefore, ΔE°cell

= E°(Cu²⁺/Cu) - E°(Cd²⁺/Cd) = +0.337 - (-0.403) V= +0.740 V

The relationship between the cell emf, Ecell, the standard emf, E°cell, and the reaction quotient, Q, is given by:

Nernst equation Ecell

= E°cell - (RT/nF) ln(Q)Q = [(Cd²+)][Cu] / [(Cd)(Cu²⁺)]

Given:

a = 0.010 =[Cd²+] = [Cu²+] = a = 0.010 M[Cd] = [Cu] = 1 - a = 0.990 M

Now,Q = [(Cd²+)][Cu] / [(Cd)(Cu²⁺)] = (0.010)² / [(0.990)(0.010)] = 0.0102

Putting the values in the Nernst equation:

Ecell = E°cell - (RT/nF) ln(Q)   Ecell = 0.740 - (0.0257/2) ln(0.0102)  = 0.740 - (0.01285) ln(0.0102)   Ecell = 0.740 - (-0.0121)   Ecell = 0.752 V.

C(s)/ R(s) 10(s + 1)/ (s + 2)(s + 5) Clearly, the closed-loop poles are located at s = -2 ands = -S, and the system is not oscillatory.
Show in MATLAB that the closed-loop frequency response of this system will exhibit a resonant peak, although the damping ratio of the closed-loop poles is greater than unity.

Answers

To show that the closed-loop frequency response of the system will exhibit a resonant peak, plot the frequency response of the system using MATLAB. Here's:

num = 10 * [1 1];     % Numerator coefficients of the transfer function

den = conv([1 2], [1 5]);   % Denominator coefficients of the transfer function

sys = t.f(num, den);   % Create the transfer function

% Plot the frequency response

bode(sys);

This 'code' defines the numerator and denominator coefficients of the transfer function and creates a transfer function object (sys). Then, it uses the 'bode' function to plot the frequency response (magnitude and phase) of the system.

An 8 µF capacitor is being charged by a 400 V supply through 0.1 mega-ohm resistor. How long will it take the capacitor to develop a p.d. of 300 V? Also what fraction of the final energy is stored in the capacitor?

Answers

Given Capacitance C = 8 μF = 8 × 10⁻⁶ F Voltage, V = 400 V Resistance, R = 0.1 MΩ = 0.1 × 10⁶ ΩNow, we have to calculate the time taken by the capacitor to develop a p.d. of 300 V.T = RC ln(1 + Vc/V).

Where R is the resistance  C is the capacitance V is the voltage of the supply Vc is the final voltage across the capacitor ln is the natural logarithm T is the time So, let's put the given values in the above formula. T = RC ln(1 + V c/V)T = 0.1 × 10⁶ × 8 × 10⁻⁶ ln(1 + 300/400)T = 0.8 ln(1.75)T = 0.8 × 0.5596T = 0.4477 seconds.

It takes 0.4477 seconds to charge the capacitor to a potential difference of 300 V. Next, we need to find the fraction of final energy that is stored in the capacitor. The energy stored in the capacitor is given as: Energy stored = (1/2) CV²Where C is capacitance and V is the voltage across the capacitor. Using the above formula.
