Air enters the compressor of an ideal air-standard Brayton cycle at 100 kPa, 300 K, with a volumetric flow rate of 5 m3/s. The turbine inlet temperature is 1400 K. For a compressor pressure ratio of 9, determine:
(a) the percent thermal efficiency of the cycle.
(b) the back work ratio.
(c) the net power developed, in kW.
(a) The percent thermal efficiency of the cycle is 33.3%.
(b) The back work ratio is 0.25.
(c) The net power developed is 4.5 kW.
