Super-heated water steam at 6 MPa and 400C enters a turbine with a velocity 50 m/s. It leaves the turbine at 70 kPa and 90% quality with a velocity of 200 m/s. The mass flow rate of steam is 20 kg/s. The rate of heat loss from turbine to surroundings amounts to 120 kJ/s. Determine 1) the enthalpy of the steam h2 at the exit. 2) The total power output of the turbine (in terms of kW)
