Seventy grams per second of air flows through a gas turbine, expanding from 1400 kPa to 101 kPa in a reversible polytropic manner. The air velocity at the inlet is 100 m/s at a temperature of 2200 K while the air velocity at the exit is 900 m/s. If the polytrpoic exponent n is 1.5. Determine the generated power, the rate of the heat transfer, the rate of the enthalpy change, and the rate of entropy change.
