Air enters the compressor of a regenerative air-standard brayton cycle with a volumetric flow rate of 100 m3/s at 0.8 bar, 280 k. the compressor pressure ratio is 20, and the maximum cycle temperature is 1950 k. for the compressor, the isentropic efficiency is 92% and for the turbine the isentropic efficiency is 95%. for a regenerator effectiveness of 86%, determine: (a) the net power developed, in mw. (b) the rate of heat addition in the combustor, in mw. (c) the percent thermal efficiency of the cycle.
