A steam turbine is operating at a steady state with a mass flow rate of 3682 kg/h at the inlet. The power output of the turbine is 8700 kW. Steam enters the turbine at a pressure of 40 bar, temperature of 320 oC, and with a velocity of 13 m/s. The exit conditions from the turbine are characterized by a pressure of 0.1 bar and the quality 90% with the velocity of 27 m/s. Determine the heat transfer rate between the turbine and surroundings, in kW.
