Question:

Use EES to solve Problem 9.63 with a variable pressure ratio. Plot the thermal efficiency as a function of pressure ratio from 10 to 15. Use six different values of the pressure ratio to generate a smooth curve.



Problem 9.63


Consider a gas-turbine engine operating with 30 kg/s of air entering at 300 K and a pressure ratio of 12.5. Using an ideal air-standard cycle as a model of this engine, determine the ideal thermal efficiency and the net shaft power delivered to the load. Assume the turbine inlet temperature is 1050 k.
