A turbine operates under steady flow conditions, receiving steam at the following state: pressure 1200 kPa, temperature 1880C, enthalpy 2785 kJ/kg, speed 33.3 m/s, and elevation 3 m. The steam leaves the turbine at the following pressure 20 kPa, enthalpy 2512 kJ/kg, speed 100 m/s, and elevation 0 m. Heat is lost to the surroundings at the rate of 0.29 kJ/s. If the rate of steam flow through the turbine is 0.42 kg/s, what is the power output of the turbine in kW?
