Air enters the compressor of an air-standard Brayton cycle with a volumetric flow rate of 60 m3/s at 0.8 bar, 280 K. The compressor pressure ratio is 20, and the maximum cycle temperature is 1800 K. For the compressor, the isentropic efficiency is 92% and for the turbine the isentropic efficiency is 95%. Determine: (a) the net power developed, in kW. (b) the rate of heat addition in the combustor, in kW. (c) the percent thermal efficiency of the cycle.
