On the basis of an air-standard (NOT cold air-standard) analysis, calculate The thermal efficiency of the cycle. The net power developed, in Btu/h.

Air enters the compressor of a simple gas turbine at p1= 14 lbf/in.2, T1 = 520degreeR, 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 (NOT cold air-standard) analysis, calculate The thermal efficiency of the cycle. The net power developed, in Btu/h.
