Question 1
Which of the following statements correctly defines a closed thermodynamic system?
Correct Answer:
A system that allows energy transfer but not mass transfer across its boundaries.
Question 2
A heat engine operates between a high-temperature reservoir at 800 K and a low-temperature reservoir at 300 K. What is the maximum possible thermal efficiency of this engine?
Correct Answer:
62.5%
Question 3
Heat transfer through a solid material by molecular vibration and collision without any net movement of the material itself is known as:
Correct Answer:
Conduction
Question 4
Steam enters a turbine at 5 MPa, 400 °C, and leaves at 10 kPa as saturated vapor. If the turbine produces 2 MW of power, and heat loss from the turbine is negligible, what is the mass flow rate of the steam? (Assume h1 = 3195.7 kJ/kg, h2 = 2583.9 kJ/kg for inlet and outlet respectively).
Correct Answer:
3.26 kg/s
Question 5
An adiabatic steam turbine operates with an inlet state of 4 MPa, 500 °C (h1 = 3446 kJ/kg, s1 = 7.090 kJ/kg·K) and an outlet pressure of 10 kPa. If the actual specific work output is 850 kJ/kg, what is the isentropic efficiency of the turbine? (At 10 kPa, h_f = 191.8 kJ/kg, h_fg = 2392.1 kJ/kg, s_f = 0.649 kJ/kg·K, s_fg = 7.501 kJ/kg·K).
Correct Answer:
70.8%
