Air enters the compressor of an air-standard Brayton cycle at P₁ = 14 lbf/in.², T₁ = 520°R, and a volumetric flow rate of 10,000 ft³/min. The isentropic efficiencies of the compressor and turbine are 83 and 87%, respectively. The compressor pressure ratio is 14 and the temperature at the turbine inlet is 2500°R. On the basis of an air-standard analysis, calculate (a) the thermal efficiency of the cycle. (b) the net power developed, in hp.
