Air enter the compressor of a referative air standard Brayton cycle with a volumetric flow rate of 60 m^3/s at 0.8 bar, 280 K. The compressor pressure ratio is 20, and the max 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
