Hot combustion gases, modeled as air behaving as an ideal gas, enter a turbine at 145 lbf/in.², 2700°R with a mass flow rate of 0.72 lb/s and exit at 29 lbf/in.² and 1620°R. If heat transfer from the turbine to its surroundings occurs at a rate of 45.82 Btu/s, determine the power output of the turbine, in hp. W cv = CV i hp
