In a simple closed circuit gas turbine engine the compressor temperature is 288 K and the turbine inlet temperature 1273 K. The isentropic efficiencies of compressor and turbine are 75% and 85% respectively and the pressure ratio is 4. Determine the overall efficiency and the specific output assuming the working fluid to be air for which Cp = 1010 J/(kg K) and y = 1.4 [0,2095; 169KJ/kg]
