Assume isentropic operations for all compressor and the turbine stages and use constant specific heats at room temperature. specific heats at room temperature. A gas turbine operates with a regenerator and two stages of reheating and intercooling. Airenters this engine at 14 psia and 60°F; the pressure ratio for each stage of compression is 4.35; the air temperature when entering a turbine is 940°F; and the regenerator operates perfectly. Determine the mass flow rate of the air passing through this engine, and the rates of heat addition and rejection when this engine produces 1,000 hp.
