A Brayton cycle with a regenerator uses air as the working fluid. The air enters the compressor at 283K and 0.1 MPa. The highest temperature in the cycle is 1073K and the pressure ratio across the compressor is 8. The isentropic efficiency of the compressor is 87% and 93% for the turbine. The air exiting the cool side of the regenerator is 10C cooler than the air entering the hot side. The cycle produces 150kW of power.
Using Constant specific heats
Determine:
a) The effectiveness of the regenerator
b) The mass flow rate through the system
c) The rate of heat addition
d) The rate of heat rejection
