Air enters the compressor of an ideal cold air-standard Brayton cycle at 100 kPa, 300 K, with a mass flow rate of 6 kg/s. The compressor pressure ratio is 10, and the turbine inlet temperature is 1000 K. For k=1.4 and C₂ 1.005 kJ/kg, calculate: (a) the percent thermal efficiency of the cycle. (b) the back work ratio. (c) the net power developed, in kW.
