Air enters the compressor of a regenerative 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 2100 k. for the compressor, the isentropic efficiency is 92% and for the turbine the isentropic efficiency is 95%. for a regenerator effectiveness of 85%, determine
(a) the net power developed, in mw.
(b) the rate of heat addition in the combustor, in mw.
(c) the thermal efficiency of the cycle.
