A gas turbine operates with a regenerator and two stages of reheating and intercooling. Air enters this engine at 14 psia and 60°F. The pressure ratio for EACH stage of compression is 3. The air temperature when entering a turbine is 940°F, and the regenerator operates perfectly. The isentropic efficiency of each turbine is 88% and that of each turbine is 93%. The cycle produces 1000 hp. Use constant specific heats at room temperature. Find the mass flow rate of the air, the rates of heat addition and rejection, and the thermal efficiency.
