In a gas turbine operating at a steady state, air enters the compressor with a mass flow rate of 5 kg/s at .95 bar and 22 C and exits at 5.7 bar. The air then passes through a heat exchange before entering the turbine at 1100 K, 5.7 bar. Air exits the turbine at .95 bar. The compressor and turbine operate adiabatically and the kinetic and potential energy effects can be ignored. The capacity ratio k in the compressor and turbine is 1.4 for air, cp is 1.013 kj/kg.K in the compressor, cp is 1.1 kj/kg.k in the turbine. Determine the net power by the plant in kw if
a. the compressor and turbine operate without internal irreversibilities.
b. the compressor and turbine isentropic efficiencies are 82% and 85%.
