In the gas turbine cycle whose installation scheme is given in the figure below, 80% Isentropically efficient high pressure turbine with only 75% isentropic efficiency It works to give enough power for the compressor. At intermediate pressure, 85% The air entering the isentropically efficient low pressure turbine is expanding. Other information on the cycle where the pressure ratio is rp = 9 given in the figure. Regenerator efficiency is 0.6. Up to Qgiren to the combustion chamber heat is added from the source at Th = 1800 K. If from the heat exchanger The amount of heat released is thrown into the heat well at TL = 290 K. Admissions: 1. Adopt variable specific heat. 2. Compressor and turbines are adiabatic. 3. 4.
