Question:

Steam enters an adiabatic turbine steadily at 5 MPa and 540oC, with a mass flow rate of 5 kg/s and leaves at 75 kPa. The isentropic efficiency of the turbine is 0.90. Determine.
(a) The temperature at the exit of the turbine.
(b) The power output of the turbine.
(c) Draw energy and entropy flow diagrams for the turbine.
