team at a rate of 5 lbm/s enters an adiabatic turbine at 800 Psia, 1000 F and leaves at an actual condition of 10 Psia, 320 F. Calculate: a) The power out of the turbine, b) The isentropic efficiency, c) Show the process on a T-s diagram for both the actual and isentropic processes with respect to the constant pressure lines, and d) Calculate the entropy generation and irreversibility for this process. Take To=77.
