A turbine operates under steady flow conditions, receiving steam at the following state: pressure 1200 KPa, temperature 1880°C, 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. Find: A. Potential Energy 1, KJ/kg. B. Potential Energy 2 in KJ/kg. C. Kinetic Energy 1 in KJ/kg. D. Kinetic Energy 2 in KJ/kg. E. Heat Energy in KJ/kg. F. Power Output in KW.
