a gas turbine power plant operates on the simple brayton cycle between the pressure limits of 100 and 700 kPa. Air enters the compressor at 30C at a rate of 13.00kg/s and leaves at 260C. A diesel fuel with a heating value of 42000 KJ/kg is burned in the combustion chamber with an air fuel of 60 and a combustion efficiency of 97 percent. Combustion gases leave the combustion chamber and enter the turbine whose isentropic efficiency is 85 percent. Treat the combustion gagses as air and use constant specific heats at 500C. Use properties of air at 500c. Cp= 1.093 kJ/kg.K Cv= 0.806kJ/kg.K R=0.287 KJ/Kg.K and k=1.357 a) the isentropic efficiency of the compressor b) the net power output and the back work ratio c) the thermal efficiency d) second law efficiency
