Air enters the compressor of a regenerative air-standard Brayton cycle with a volumetric flow rate of 100 m?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 sentropic 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
