Explanation:

Solve Problem 1 on a cold air-standard basis with specific heats evaluated at
300 K.

1. An air-standard Otto cycle has a compression ratio of 9. At the beginning of
compression, 1 = 100 kPa and 1 = 300 K. The heat addition per unit mass
of air is 1350 kJ/kg. Determine
(a) the net work, in kJ per kg of air.
(b) the thermal efficiency of the cycle.
(c) The mean effective pressure, in kPa.
(d) The maximum temperature in the cycle, in K.

Answers

Answer:

(a) 774.529 kJ/kg

(b) Approximately 61.2%

(c) 96.816 kPa

(d) The maximum in the cycle temperature is 2655.3 K

Explanation:

(a)The temperature T₂ = T₁ × r^(k - 1)

∴ T₂ = 300 × 9^(1.4 - 1) = 772.467 K

P₂ = P₁×r×T₂/T₁ = 100 × 8 × 772.467/300 = 2059.912 kPa

W₁₂ = Cv × (T₁ - T₂) = 0.717*(300 - 772.467) ≈ -338.76 kJ/kg

The heat added = q₂₃ = 1350 kJ/kg = Cv × (T₃ - T₂) = 0.717*(T₃- 772.467)

1350/0.717 = T₃- 772.467

T₃ = 1350/0.717 + 772.467 = 2655.3 K

T₄ = T₃ × (1/r)^(k - 1) = 2655.3  × (1/9)^(1.4 - 1) = 1102.596 K

W₃₄ = Cv×(T₃ - T₄) = 0.717 × (2655.3 - 1102.596) ≈ 1113.289 kJ/kg

The net work = W₁₂ + W₃₄ = -338.76  + 1113.289 = 774.529 kJ/kg

(b) The thermal efficiency, [tex]\eta _{th}[/tex] = 1 - T₁/T₂ = (1 - 300/772.467) × 100 ≈ 61.2%

(c) The Mean Effective Pressure, MEP = (Net work)/Displacement Volume)

For unity clearance, volume, we have;

MEP = 774.529/(9 - 1) = 96.816 kPa

(d) The maximum temperature, occur at T₃ = 2655.3 K.

Force is the cause of a velocity change

Answers

The answer is true. hope this helped

Answer:

Forces affect how objects move. They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object, we can say that forces cause changes in velocity. Remember that acceleration is a change in velocity

Which option identifies what engineers will do to help in the following scenario?
After an explosion on an offshore drilling rig, engineers were called in to take action.


A) Engineers will work to design a rig that will not allow methane to escape and cause fires.

B)Engineers will create a large container to keep the flowing petroleum from entering the water.

C)Engineers will expand the drilling to divert the methane gas.

D)Engineers will work to design a system that will cap off the pipeline and stop the flow of petroleum.

Answers

Answer:

D is Correct

Explanation:

D) Engineers will work to design a system that will cap off the pipeline and stop the flow of petroleum.

In the scenario given, an explosion has occurred on an offshore drilling rig, indicating that there has been a catastrophic failure in the system. The first priority in such a situation would be to contain and stop the flow of petroleum to prevent further damage to the environment and ensure safety.

Engineers would be called in to take immediate action and design a system that will cap off the pipeline and stop the flow of petroleum. This might involve designing and installing valves or other mechanical devices that can shut off the flow of petroleum.

Option A is incorrect because preventing methane from escaping and causing fires is not the immediate priority in this situation. Option B is also incorrect because the immediate priority is to stop the flow of petroleum, not to contain it. Option C is not a feasible solution as diverting methane gas would not address the immediate issue of stopping the flow of petroleum.

Engineers will work to design a rig that will not allow methane to escape and cause fires. Thus, the correct option is A.

Thus, An engineer solves issues using math, science, and technology. Engineering is all around us, enhancing the ways that we work, travel, communicate, maintain our health, and have fun.

Engineers transform scientific information into technology, which they subsequently transform into a practical solution or innovation.

All engineers experience a sense of pride and well-being after successfully completing a challenging assignment. Making, designing, and manufacturing valuable goods and services for other people is a career that will enrich your life.

Thus, The ideal option is A.
