Power Output of the Turbine - GATE ME '01

Stream at 300 kPa and 500 C (h=3486.0 kJ/kg) enters a steam turbine and exits at atmospheric pressure and 350 C (h=3175.8 kJ/kg). Heat losses in the turbine are 50 kW and the mass flow rate is 0.25 kg/s. Determine the power output of the turbine if kinetic energy losses are negligible.
