Air enters the compressor of an ideal air standard Brayton cycle at 195 kPa, 290 K, with a volumetric flow rate of 6 m/s. The compressor pressure ratio is 9. The turbine inlet temperature is 1400 K. The compressor has an efficiency of 90% and the turbine has an efficiency of 75%. Show the cycle on a T-S diagram and determine: (A) Net power output. (B) Back work ratio. (C) Thermal efficiency of the cycle. For Air, Assume Cp = 1.005 kJ/kg.K, R = 0.287 kJ/kg.K, k = 1.4.
