Consider a Rankine cycle engine. The engine will use 0.46 kilomoles of water vapor (treated as a diatomic gas) that is initially at 1.5 atm in a 10 m3 vessel. Then, water vapor is compressed isobarically to 1/10th of its original volume. Next, the water vapor is isochorically pressurized to 5 atm. The water is then isobarically expanded to a volume of 4.23 m3. Finally, the water vapor is allowed to adiabatically expand back to its original pressure and volume. (R = 8314 J/kilomole (K); 1 atm = 101325 Pa)

a) Draw the P-V diagram for the Rankine cycle

b) Calculate the work done by the engine for one complete cycle

c) Calculate the heat absorbed by the engine

d) Calculate the efficiency of the heat engine.

e) Compare this efficiency to a Carnot Cycle operating between the two most extreme temperatures achieved by the engine.

Consider an ideal Rankine cycle using water with a high-pressure side of the cycle at a supercritical pressure. Such a cycle has a potential advantage of minimizing local temperature differences between the fluids in the steam generator, such as the instance in which the high-temperature energy source is the hot exhaust gas from a gas- turbine engine.
