Determine the efficiency of the a gas turbine plant fitted with a heat exchanger of 75% effectiveness. The pressure ratio is 4:1 and the compression is carried out in two stages of equal pressure ratio with complete intercooling back to initial temperature of 290K. The maximum temperature is 925 K. The turbine isentropic efficiency is 88% and each compressor isentropic efficiency is 85%. For air, y=1.4 and c,=1.005 kJ/kg.K [35 Marks] Inter cooler 2' Ewwww 3 3-o supply L.P. H.P.
