6) Steam enters a turbine at a pressure P-2.0MPA, temperature T=500*C and enthalpy hi=3062 kJ/kg with a velocity vi=10 m/s. The steam leaves the turbine as a gas-liquid mixture at a pressure P2=101kPa, temperature Ty-373 K, and enthalpy h;-2621 kJ/kg with a velocity of vz-50 m/s. Thermal energy is lost through the turbine walls at a rate of 5 kJ/hr. The elevation difference between the entrance and exit of the turbine can be neglected. Calculate the power output in units of kW if 4000 kg/hr of steam pass through the turbine.
