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 = 1.4 and cp = 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.
