Mechanical Engineering

Air enters the compressor of a regenerative air-standard Braytoncycle with a volumetric flow rate of 20 m3/s at 0.8 bar,280 K. The compressor pressure ratio is 20, and the maximum cycletemperature is 1950 K. For the compressor, the isentropicefficiency is 92% and for the turbine the isentropic efficiency is95%.


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.
