A mixture having a molar analysis of 66% N2, 17% CO2, and 17% H2O enters a turbine at 1000 K, 8 bar, with a mass flow rate of 2 kg/s and expands isentropically to a pressure of 1 bar. Ignoring kinetic and potential energy effects, determine for steady-state operation the temperature at the exit and the power developed by the turbine.
