Question:

Consider a 200-hp Brayton cycle using air. The compressor and turbine are both adiabatic but irreversible. There are pressure drops during heating and cooling. The following temperatures and pressures have been measured at the inlet states around the cycle:image


Assuming constant specific heats, determine:


(a) The thermal efficiency of the cycle.


(b) The mass flow rate (lbm/hr) of the air.
