Question: Rework Problem 9.37 except that the compressor exit temperature is a) 600°C b) 800°C. Air enters the gas turbine cycle of Fig. 9.44 at 25°C

Rework Problem 9.37 except that the compressor exit temperature is
a) 600°C
b) 800°C.
Air enters the gas turbine cycle of Fig. 9.44 at 25°C and 100 kPa with a flow rate of 1.2 kg/s. It is compressed so that the temperature at state 2 is 400°C. The temperature entering the turbine is 1400ºC. Assuming constant specific heats for the air and ideal conditions in all components, calculate:
i) The thermal efficiency
ii) The heat added in the combustor
iii) The net power produced by the cycle
iv) The back-work ratio
