Combustion products from a burner enter a gas turbine at 10 bar and 950°C and
discharge at 1.5 bar. The turbine operates adiabatically with an efficiency of 77%.
Assuming the combustion products to be an ideal-gas mixture with a heat capacity
of 32 J⋅mol−1⋅K−1, what is the work output of the turbine per mole of gas, and what
is the temperature of the gases discharging from the turbine?
