The Brayton cycle has regeneration, intercooling and reheat. Air enters the cycle at the inlet of the first compressor at 300 K and 100 kPa. The regenerator effectiveness is 80 percent. The compressor pressure ratio across each compressor is 10. The air leaves the intercooler at 300K. The pressure of the reheater is the same as the pressure in the intercooler. Air enters each turbine at 1500 K. Each compressor has an isentropic efficiency of 90 percent, and each turbine has an isentropic efficiency of 85 percent.Determine the following:
(a) Net power per mass flow rate
(b) Thermal cycle efficiency
(c) Back work ratio
