A power plant operates on the air standard Brayton cycle with regeneration. Air enters the compressor at 14.5 psi and 537 R, and it leaves the compressor at 60 psia. The air exits the regenerator at 1120 R, and it exits the combustion chamber at 1700 R. The compressor and turbine each have an isentropic efficiency of 0.85. The mass flow of the air is 17.8 lbm/s. a. Sketch the corresponding T-s diagram.
b. Calculate the thermal efficiency of the cycle.
c. Calculate back work ratio.
d. Calculate the regenerator effectiveness.
e. Calculate the mass flow rate of the air, in lb/s.
