Combustion gases enter an insulated turbine operating at steady state at 12 bar, 1500 K with a mass flow rate of 1 kg/s and are expanded to 1 bar, 980 K. The combustion gases can be considered to be an ideal gas mixture with a composition on a molar basis of 9.5% CO2 and 19% H2O and the balance being N2. Kinetic and potential energy effects can be considered negligible Determine:
(a) the turbine isentropic efficiency
(b) the turbine power, in kW.
(c) the rate of entropy production, in kW/K.
