Steam enters an adiabatic turbine steadily at 3 MPa and
400°C and leaves at 50 kPa. If the isentropic efficiency of the
turbine is 66.7%, determine the actual temperature of steam at
turbine exit. The mass flow rate of the steam flowing through the
turbine is 218 kg/min, determine the power output from the turbine.
