In a steam turbine, steam is flowing at 20kg/s. At the inlet of the turbine, specific enthalpy is 2800kJ/kg, velocity 20m/s and heigh is 2m. At the outlet, specific enthalpy is 1900kJ/kg, velocity is 150m/s and the height is 0m. In addition, from this turbine, 300kJ/s of heat is being released. Obtain the turbine output power. (the effective work the turbine does per second).
