An open cycle gas turbine has a single stage compressor and a single stage expander incorporating a heat exchanger. The air suction temperature is 17 degree Celsius and the pressure1 bar. For an overall pressure ratio o f 4.5 and the shaft output of 4000kW the mass flow is 40kg/s. if the thermal ratio of the heat exchanger is 0.6 and the isentropic efficiency of the compressor is 0.84 calculate the isentropic efficiency of the gas turbine for a plant thermal efficiency of 0.29. Take for air y=14, Cpa=1.005 kJ/kg K for gas y=1.365, Cpg=1.07 kJ/kg K
