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
