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 1400 K. For k 5 1.4, calculate
(a) the thermal efficiency of the cycle.
(b) the back work ratio.
(c) the net power developed, in kW.
