The recommended baghouse type that can be used to retrofit a plant limited in space and needs to achieve a particle control efficiency of 95% is a pulse jet baghouse.

In order to recommend a baghouse type to retrofit a plant that is limited in space and needs to achieve particle control efficiency of 95%, let us first look at the baghouse options available and their efficiency. A baghouse is an air pollution control device that uses fabric filter tubes to remove particulate matter from the air and gases. There are three types of baghouses that can be used: Shaker Baghouse, Reverse Air Baghouse and Pulse Jet Baghouse.

Shaker baghouses are generally smaller than other baghouse designs and have low initial capital costs. The downside of this type of baghouse is that it has the lowest efficiency compared to reverse air and pulse jet baghouses. This means that it may not be able to achieve the required 95% particle control efficiency.

Reverse Air Baghouse is more efficient than the shaker baghouse. The reverse air baghouse features a cleaning system that uses an adjustable fan to pull air through the baghouse, effectively dislodging the collected dust particles. The collected particles are then discharged to a hopper for storage or disposal. This baghouse type can achieve a particle control efficiency of up to 99%.

However, in our case, it is recommended to use a Pulse Jet Baghouse. This type of baghouse is the most efficient and provides the highest level of particle control efficiency of up to 99.9%. Pulse jet baghouses use high-pressure compressed air to pulse the bags, causing the dust to fall into the hopper below. Pulse jet baghouses have lower operating costs than other types of baghouses due to their smaller size, less frequent cleaning cycles, and use of less compressed air.

Therefore, considering the limitation of space and the required particle control efficiency of 95%, pulse jet baghouse is the best recommendation.

Conclusion: The recommended baghouse type that can be used to retrofit a plant limited in space and needs to achieve a particle control efficiency of 95% is a pulse jet baghouse.

a. The shear flow at a point 100mm below the top of the beam is 0.76 N/mm².

b. The maximum shearing stress of the beam is 0.76 N/mm².

a. To determine the shear flow at a point 100mm below the top of the beam, we can use the formula:

Shear Flow (q) = Shear Force (V) / Area (A)

Shear Force (V) = 95 kN

Beam section dimensions: 250mm x 500mm

Calculate the area of the beam section.

Area (A) = width × height

Area (A) = 250mm × 500mm = 125,000 mm²

Convert the shear force to N (Newtons) for consistency.

Shear Force (V) = 95 kN = 95,000 N

Calculate the shear flow.

Shear Flow (q) = Shear Force (V) / Area (A)

Shear Flow (q) = 95,000 N / 125,000 mm²

Now, we can substitute the appropriate units for consistency and simplify the result:

Shear Flow (q) = (95,000 N) / (125,000 mm²) = 0.76 N/mm²

Therefore, the shear flow at a point 100mm below the top of the beam is 0.76 N/mm².

b. To find the maximum shearing stress of the beam, we can use the formula:

Maximum Shearing Stress = Shear Force (V) / Area (A)

Shear Force (V) = 95 kN

Beam section dimensions: 250mm x 500mm

Calculate the area of the beam section.

Area (A) = width × height

Area (A) = 250mm × 500mm = 125,000 mm²

Convert the shear force to N (Newtons) for consistency.

Shear Force (V) = 95 kN = 95,000 N

Calculate the maximum shearing stress.

Maximum Shearing Stress = Shear Force (V) / Area (A)

Maximum Shearing Stress = 95,000 N / 125,000 mm²

Now, we can substitute the appropriate units for consistency and simplify the result:

Maximum Shearing Stress = (95,000 N) / (125,000 mm²) = 0.76 N/mm²

Therefore, the maximum shearing stress of the beam is 0.76 N/mm².

The unit weight of the body floating in kN/m3 is (240V) / 9.81, where V is the total volume of the body.

The specific gravity of a liquid is the ratio of its density to the density of water. In this case, the specific gravity of the liquid in which the body floats is given as 0.8. To determine the unit weight of the body in kN/m3, we need to consider the volume of the body that is submerged in the liquid. The question states that 3/4 of the volume of the body is submerged. Let's assume the total volume of the body is V. Since 3/4 of the volume is submerged, the volume of the submerged part is (3/4)V. The weight of the body is equal to the weight of the liquid displaced by the submerged part of the body. According to Archimedes' principle, the weight of the liquid displaced is equal to the weight of the body.

The weight of the body can be calculated using the formula: Weight = Volume x Specific gravity x Density of water. The density of water is approximately 1000 kg/m3. Substituting the values into the formula, we get: Weight = (3/4)V x 0.8 x 1000 kg/m3. Now, we need to convert the weight from kg/m3 to kN/m3. 1 kN is equal to 1000 N, and 1 N is equal to 1 kg.m/s2. Therefore, 1 kN is equal to 1000 kg.m/s2. To convert the weight from kg/m3 to kN/m3, we divide by 9.81 (the acceleration due to gravity): Weight (kN/m3) = ((3/4)V x 0.8 x 1000) / 9.81. Simplifying the equation, we get: Weight (kN/m3) = (240V) / 9.81. So, the unit weight of the body in kN/m3 is (240V) / 9.81, where V is the total volume of the body.

The area of rebar is approximately 17,333.86 mm^2

To determine the area of rebar in mm2, we need to consider the factored moment and the properties of the reinforcement.

Step 1: Calculate the effective depth of the slab.
Effective depth (d) = total thickness of the slab - clear concrete cover
d = 120 mm - 20 mm
d = 100 mm

Step 2: Calculate the lever arm (a).
Lever arm (a) = (d/2) + (d/6)
a = (100 mm/2) + (100 mm/6)
a = 50 mm + 16.67 mm
a = 66.67 mm

Step 3: Calculate the factored moment capacity (Mn).
Mn = (0.138 * fy * A * (d - a))/(10^6)
Where:
fy = yield strength of the reinforcement = 275 MPa
A = area of the reinforcement

We can rearrange the equation to solve for A:
A = (Mn * 10^6)/(0.138 * fy * (d - a))
A = (23 kN-m * 10^6)/(0.138 * 275 MPa * (100 mm - 66.67 mm))

Converting kN-m to N-mm:
A = (23,000 N-mm * 10^6)/(0.138 * 275 MPa * (100 mm - 66.67 mm))

Simplifying the equation:
A = (23,000,000,000 N-mm)/(37.95 MPa * 33.33 mm)

Using appropriate units for area:
A = (23,000,000,000 N-mm)/(37.95 * 10^6 N/mm^2 * 33.33 mm)
A = 17,333.86 mm^2

Apply the Euclidean Algorithm to find the greatest common divisor (GCD) of 1176 and 1976:
1976 = 1 * 1176 + 800
1176 = 1 * 800 + 376
800 = 2 * 376 + 48
376 = 7 * 48 + 20
48 = 2 * 20 + 8
20 = 2 * 8 + 4
8 = 2 * 4

The GCD of 1176 and 1976 is 4.

Divide the original equation by the GCD:
(1176/4)x + (1976/4)y = 4152/4

2 = 2 * 1

The GCD of 2 and 3 is 1.

Divide the original equation by the GCD:
(2/1)x + (3/1)y = 7/1
2x + 3y = 7

Solve the simplified equation for one variable in terms of the other variable:
2x = 7 - 3y
x = (7 - 3y)/2

Check the range of values for x:
-10 < (7 - 3y)/2 < 10

Multiply all sides of the inequality by 2:
-20 < 7 - 3y < 20

Subtract 7 from all sides of the inequality:
-27 < -3y < 13

Divide all sides of the inequality by -3 (note the change in direction of the inequality):
9 > y > -4

Therefore, the values of y that satisfy the inequality are:

I. Yield of a dam refers to the amount of water that a dam can supply over a specific period of time. It is typically measured in terms of cubic meters or acre-feet. The yield of a dam depends on various factors such as the catchment area, rainfall patterns, and evaporation rates.

II. Firm yield represents the reliable and consistent amount of water that a dam can provide under normal conditions. It takes into account the average inflow and outflow of water throughout the year, ensuring a steady supply for various purposes such as irrigation, drinking water, and hydropower generation.

III. Secondary yield refers to the additional water that can be made available from a dam by implementing certain measures such as efficient water management practices, use of groundwater resources, or implementing recycling and reuse strategies. This additional yield can be used to meet increased water demands or for other purposes.

IV. Safe yield refers to the maximum amount of water that can be withdrawn from a dam without causing detrimental effects on the dam structure or the surrounding environment. It is important to determine the safe yield to ensure the sustainability and longevity of the dam while also considering the needs of water users.

For example, let's consider a dam with a yield of 1000 acre-feet. The firm yield could be determined as 800 acre-feet, which is the reliable amount of water that can be supplied under normal conditions. However, through efficient water management practices, an additional 200 acre-feet could be obtained as secondary yield. The safe yield, in this case, would be determined by assessing the dam's structural capacity and the ecological impact of withdrawing water, ensuring that it doesn't exceed a certain limit, let's say 900 acre-feet.

In summary, yield of a dam refers to the amount of water it can supply. Firm yield represents the reliable supply, secondary yield is the additional supply through management practices, and safe yield is the maximum withdrawal limit to ensure sustainability.

Using strong induction, we have proved that T(N) ≤ NlogN + N for all N ≥ 1, where T(N) is defined as T(N) = 2T(floor(N/2)) + N with the base case T(1) = 1.

To prove that T(N) ≤ NlogN + N for all N ≥ 1, we will use strong induction.

Base case:

For N = 1, we have T(1) = 1, which satisfies the inequality T(N) ≤ NlogN + N.

Inductive hypothesis:

Assume that for all k, where 1 ≤ k ≤ m, we have T(k) ≤ klogk + k.

Inductive step:

We need to show that T(m + 1) ≤ (m + 1)log(m + 1) + (m + 1) using the inductive hypothesis.

From the given recurrence relation, we have T(N) = 2T(floor(N/2)) + N.

Applying the inductive hypothesis, we have:

2T(floor((m + 1)/2)) + (m + 1) ≤ 2(floor((m + 1)/2)log(floor((m + 1)/2)) + floor((m + 1)/2)) + (m + 1).

We know that floor((m + 1)/2) ≤ (m + 1)/2, so we can further simplify:

2(floor((m + 1)/2)log(floor((m + 1)/2)) + floor((m + 1)/2)) + (m + 1) ≤ 2((m + 1)/2)log((m + 1)/2) + (m + 1).

Next, we will manipulate the logarithmic expression:

2((m + 1)/2)log((m + 1)/2) + (m + 1) = (m + 1)log((m + 1)/2) + (m + 1) = (m + 1)(log(m + 1) - log(2)) + (m + 1) = (m + 1)log(m + 1) + (m + 1) - (m + 1)log(2) + (m + 1) = (m + 1)log(m + 1) + (m + 1)(1 - log(2)).

Since 1 - log(2) is a constant, we can rewrite it as c:

(m + 1)log(m + 1) + (m + 1)(1 - log(2)) = (m + 1)log(m + 1) + c(m + 1).

Therefore, we have:

T(m + 1) ≤ (m + 1)log(m + 1) + c(m + 1).

By the principle of strong induction, we conclude that T(N) ≤ NlogN + N for all N ≥ 1.

We used strong induction because the inductive hypothesis assumed the truth of the statement for all values up to a given integer (from 1 to m), and then we proved the statement for the next integer (m + 1).

To draw the shear and moment diagrams for each member of the frame with pin connections at A, B, and C, follow the steps outlined below.

To draw the shear and moment diagrams for each member of the frame, you need to analyze the forces and moments acting on the individual members. Here's a step-by-step breakdown of the process:

1. Determine the support reactions: Start by calculating the reactions at the pin connections A, B, and C. These reactions will provide the necessary boundary conditions for further analysis.

2. Cut each member and isolate it: For each member of the frame, cut it at the connections and isolate it as a separate beam. This allows you to analyze the forces and moments acting on that particular member.

3. Draw the shear diagram: Begin by drawing the shear diagram for each isolated member. The shear diagram shows how the shear force varies along the length of the member. To construct the shear diagram, consider the applied loads, reactions, and any point loads or moments acting on the member. Start from one end of the member and work your way to the other end, plotting the shear forces at different locations.

4. Draw the moment diagram: Once the shear diagram is complete, proceed to draw the moment diagram for each member. The moment diagram shows how the bending moment varies along the length of the member. To construct the moment diagram, integrate the shear forces from the shear diagram. The resulting values represent the bending moments at different locations along the member.

The water of crystallization for this hydrated compound is 1.09.

To calculate the water of crystallization for the hydrate of chromium(II) sulfate (CrSO4 XH2O), we need to use the given information that the hydrate decomposes to produce 19.6% water and 80.4% anhydrous compound (AC).

First, let's assume we have 100 grams of the hydrate compound.

From the given information, we know that 19.6 grams of the hydrate compound is water and 80.4 grams is the anhydrous compound (AC).

To find the molar mass of water, we add the molar masses of hydrogen (H) and oxygen (O), which are 1 g/mol and 16 g/mol, respectively. Therefore, the molar mass of water is 18 g/mol.

Next, we need to find the number of moles of water present in the 19.6 grams. We divide the mass of water by its molar mass:

19.6 g / 18 g/mol = 1.09 moles of water.

Since the ratio between the water and the anhydrous compound in the formula is 1:1 (CrSO4 XH2O), we can conclude that 1.09 moles of water corresponds to 1.09 moles of the anhydrous compound.

The molar mass of the anhydrous compound (CrSO4) is given as 148.1 g/mol.

Now, we can find the mass of the anhydrous compound in the 80.4 grams:

80.4 g * (148.1 g/mol / 1 mol) = 11914.24 g/mol.

To find the molar mass of the water of crystallization (XH2O), we subtract the mass of the anhydrous compound from the total mass of the hydrate:

100 g - 80.4 g = 19.6 g of water of crystallization.

Finally, we need to find the number of moles of water of crystallization. We divide the mass of water of crystallization by its molar mass:

19.6 g / 18 g/mol = 1.09 moles of water of crystallization.

Since 1.09 moles of water of crystallization corresponds to 1.09 moles of the anhydrous compound, we can conclude that the water of crystallization for this hydrated compound is 1.09.

Therefore, the answer is 1.09.

The flow depth along the narrow section is given as [tex]\frac{13.64 + 2.2a}{5.2 + a}[/tex] meters.

To calculate the flow depth along the narrow section, we have to make use of principle of continuity, which states that product of cross-section area and velocity of fluid remains constant. Let's assume flow depth along the narrow section as 'h'. The cross-sectional area of the channel is:

A' = (5.2 + a) * h

We can set up the equation as:

A * h = A' * h'

By substituting the given values, we have:

(6.2 + a) * 2.2 = (5.2 + a) * h'

h' = [(6.2 + a) * 2.2] / (5.2 + a)

The function with a cusp at the origin is 01/3.

A cusp occurs at a point where the function's first derivative is undefined or equal to zero. To determine this, we need to find the derivative of each function and evaluate it at the origin.

The derivative of 0-1/3 is zero since the constant term does not affect the derivative.

The derivative of 01/s is -1/s^2, which is undefined at the origin (s=0).

The derivative of 01/3 is zero since it is a constant.

The derivative of 02/5 is also zero since it is a constant.

Therefore, only the function 01/3 has a cusp at the origin, as its derivative is zero. It's worth noting that a cusp is a point of discontinuity in the slope of a function, often resulting in a sharp bend or corner in the graph.

1,4-butanediol would have the highest solubility in water due to the presence of hydroxyl groups, molecular weight, and polarity.

The compound with the highest solubility in water would be 1,4-butanediol.

Here's why:

1. Hydrogen bonding: 1,4-butanediol contains multiple hydroxyl (-OH) groups, which can form hydrogen bonds with water molecules. Hydrogen bonding is a strong intermolecular force that enhances solubility in water. Pentanol also contains an -OH group, but it has a longer carbon chain, making the hydroxyl group less accessible to form hydrogen bonds with water molecules.

2. Molecular weight: 1,4-butanediol has a molecular weight of 90 g/mol, which is relatively lower compared to the other compounds. Generally, compounds with lower molecular weights have higher solubility in water because they can be more easily surrounded and dispersed by water molecules.

3. Polarity: 1,4-butanediol is a polar compound due to the presence of the hydroxyl groups. Water is also a polar molecule. Like dissolves like, so polar compounds tend to dissolve well in polar solvents like water.

On the other hand, ethane and dimethyl ether 1 have lower solubility in water. Ethane is a nonpolar molecule, lacking any functional groups that can interact with water molecules. Dimethyl ether 1 is also nonpolar and has a lower molecular weight than 1,4-butanediol, but it lacks the hydroxyl groups that contribute to hydrogen bonding.

In summary, 1,4-butanediol would have the highest solubility in water due to the presence of hydroxyl groups, molecular weight, and polarity.

a) The initial volume is approximately 898.73 ft^3 and the final volume is approximately 3145.24 ft^3.
b) The net amount of energy transferred to the gas is approximately 182 Btu.
c) The amount of time the heater is operated is approximately 0.14 hours.

The initial conditions of the piston-cylinder device are as follows:
- Mass of R-134a: 1.3 lbm
- Initial pressure: 80 psia
- Initial temperature: 200 °F

To calculate the initial volume, we need to use the ideal gas law equation, which states that PV = mRT, where P is the pressure, V is the volume, m is the mass, R is the specific gas constant, and T is the temperature.

First, we need to convert the mass from lbm to slugs. The conversion factor is 1 lbm = 0.03108 slugs.

Mass of R-134a in slugs = 1.3 lbm × 0.03108 slugs/lbm = 0.040404 slugs

Next, we need to convert the temperature from °F to Rankine (R), which is the absolute temperature scale. The conversion factor is °F + 459.67 = R.

Initial temperature in R = 200 °F + 459.67 = 659.67 R

Now, we can calculate the initial volume using the ideal gas law equation:

Initial volume = (mass of R-134a × R × initial temperature) / initial pressure
Initial volume = (0.040404 slugs × 1716.56 ft·lbf/(slug·R) × 659.67 R) / 80 psia
Initial volume ≈ 898.73 ft^3 (rounded to two decimal places)

The final conditions of the piston-cylinder device are as follows:
- Final temperature: 700 °F

To calculate the final volume, we can use the ideal gas law equation again. However, since the pressure remains constant, we can simplify the equation to V1 / T1 = V2 / T2, where V1 and T1 are the initial volume and temperature, and V2 and T2 are the final volume and temperature.

Using this equation, we can solve for the final volume:

Final volume = (initial volume × final temperature) / initial temperature
Final volume = (898.73 ft^3 × 700 °F) / 200 °F
Final volume ≈ 3145.24 ft^3 (rounded to two decimal places)

Now, let's move on to part b.

To calculate the net amount of energy transferred to the gas, we need to use the equation Q = mcΔT, where Q is the energy transferred, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature.

First, let's find the change in temperature:

ΔT = final temperature - initial temperature
ΔT = 700 °F - 200 °F
ΔT = 500 °F

The specific heat capacity of R-134a at constant pressure is approximately 0.28 Btu/(lbm·°F).

Now, we can calculate the energy transferred:

Energy transferred = mass × specific heat capacity × ΔT
Energy transferred = 1.3 lbm × 0.28 Btu/(lbm·°F) × 500 °F
Energy transferred ≈ 182 Btu (rounded to the nearest whole number)

Finally, let's move on to part c.

To calculate the amount of time the heater is operated, we need to use the equation P = E / t, where P is the power, E is the energy transferred, and t is the time.

The power of the electric heater is given as 350 watts.

Now, we can calculate the time:

Time = energy transferred / power
Time = 182 Btu / 350 watts

To convert watts to Btu, we can use the conversion factor 1 Btu = 0.29307107 watts.

Time = 182 Btu / (350 watts × 0.29307107 Btu/watt)
Time ≈ 0.14 hours (rounded to two decimal places)

The total number of moles of H+ available for reaction in 1.50 L of 0.500 M H3PO4 is 2.25 moles of H+.

Phosphoric acid is a triprotic acid, H3PO4. In this acid, three H+ ions can be released. It is referred to as a triprotic acid because it can release three hydrogen ions, as it contains three hydrogen atoms that can ionize. The three hydrogen ions are released one after the other, with the first ionization reaction being the strongest.

Following are the three ionization reactions:

H3PO4(aq) + H2O(l) → H3O+(aq) + H2PO4−(aq)

Ka1 = 7.5 × 10−3H2PO4−(aq) + H2O(l) → H3O+(aq) + HPO42−(aq)

Ka2 = 6.2 × 10−8HPO42−(aq) + H2O(l) → H3O+(aq) + PO43−(aq)

Ka3 = 4.2 × 10−13

It is given that the concentration of H3PO4 is 0.500 M and the volume of H3PO4 is 1.50 L.

Molar mass of H3PO4 = 3 × 1.01 + 30.97 + 4 × 16.00 = 98.00 g mol-1

Number of moles of H3PO4 = Molarity × Volume

= 0.500 M × 1.50 L

= 0.75 moles

Total number of moles of H+ available for reaction = 3 × 0.75 moles = 2.25 moles of H+.

The flow line is represented by a long arrow pointing in the direction of the higher elevation.

17. Calculation of the hydraulic gradient between wells A and B:

To compute the hydraulic gradient between wells A and B, use the following equation:

Hydraulic gradient = (ΔH / ΔL) * 1000 meters/km

Where ΔH = the difference in head (hydraulic) between two points, which is 25 meters in this example.

ΔL = the distance between the two points, which is 4 cm on the map.

The map's scale is 1 cm = 1500 m,

thus 4 cm = 4 * 1500 = 6000 m.

Using the equation above, the hydraulic gradient between wells A and B is as follows:

Hydraulic gradient = (ΔH / ΔL) * 1000 meters/km

= (25 m / 6000 m) * 1000 meters/km

= 0.004167 m/km

Answer:  the general solution of the system x' = Ax is given by:

                x(t) = c1 * e^(2t) * [1, -5] + c2 * e^(13t) * [9/2, 2]

The general solution of the system x' = Ax, where A = [[7, 1], [2, 4]], can be found by solving the characteristic equation of the matrix A.

To solve the characteristic equation, we start by finding the eigenvalues of A. The eigenvalues are the solutions to the equation det(A - λI) = 0, where λ is the eigenvalue and I is the identity matrix.

Substituting the values of A, we get:

det([[7, 1], [2, 4]] - λ[[1, 0], [0, 1]]) = 0

Expanding the determinant, we have:

(7 - λ)(4 - λ) - (1)(2) = 0

Simplifying the equation, we get:

(λ - 7)(λ - 4) - 2 = 0

Expanding and simplifying further, we get:

λ^2 - 11λ + 26 = 0

Now, we solve this quadratic equation to find the eigenvalues. We can factorize it as:

(λ - 2)(λ - 13) = 0

So, the eigenvalues are λ = 2 and λ = 13.

Next, we find the eigenvectors corresponding to each eigenvalue. We substitute each eigenvalue back into the equation (A - λI)v = 0, where v is the eigenvector.

For λ = 2:
Substituting, we get:

[[7, 1], [2, 4]] - 2[[1, 0], [0, 1]] v = 0

Simplifying, we have:

[[5, 1], [2, 2]] v = 0

This leads to the equation:

5v1 + v2 = 0
2v1 + 2v2 = 0

Simplifying, we get:

v1 + (1/5)v2 = 0
v1 + v2 = 0

We can choose v2 = -5, which gives v1 = 1. Therefore, the eigenvector corresponding to λ = 2 is v = [1, -5].

For λ = 13:
Substituting, we get:

[[7, 1], [2, 4]] - 13[[1, 0], [0, 1]] v = 0

Simplifying, we have:

[[-6, 1], [2, -9]] v = 0

This leads to the equation:

-6v1 + v2 = 0
2v1 - 9v2 = 0

Simplifying, we get:

-6v1 + v2 = 0
2v1 = 9v2

We can choose v2 = 2, which gives v1 = 9/2. Therefore, the eigenvector corresponding to λ = 13 is v = [9/2, 2].

Finally, the general solution of the system x' = Ax is given by:

x(t) = c1 * e^(2t) * [1, -5] + c2 * e^(13t) * [9/2, 2]

where c1 and c2 are arbitrary constants.
