Forty Five grams per second of air flows through a gas turbine, expanding from 1350 kPa to 101 kPa in a reversible polytropic manner. The air velocity at the inlet is 100 m/s at a temperature of 2000 K while the air velocity at the exit is 750 m/s. If the polytrpoic exponent n is 1.38. Determine the following:
a. The total generated power.
b. The rate of the total heat transfer
c. The rate of the total enthalpy change
d. The rate of the total entropy change.
