A turbine operates under steady-flow conditions. It receives steam at a pressure of 15 bar, specific volume of 0.1318 m³/kg, velocity of 30 m/s and specific internal energy of 2594.5 kJ/kg. The steam leaves the turbine at a pressure of 30 kPa, velocity of 90 m/s, specific volume of 4.25 m³/kg and specific internal energy of 2060.3 kJ/kg. Heat is rejected to the surroundings at a rate of 2000 W. Steam flows through the turbine at a rate of 0.4 kg/s.

how would we calculate initial enthalpy and the final enthalpy, change in kinetic energy of steam (per unit mass of steam). and the power generated.
