Air enters the compressor of a regenerative air-standard Brayton
cycle with a volumetric flow rate of 20 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
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.
