Steam enters a well-insulated turbine operating a steady state operating at a steady state at 4 MPa with a specific enthalpy of 3015.4 kJ/kg and a velocity of 10 m/s. The steam expands to the turbine exit where the pressure is 0.07 MPa, specific enthalp is 2431.7 kJ/kg, and the velocity is 90 m/s. The mass flow rate is 11.9 kg/s. Neglecting potential energy effects, determine the power developed by the turbine, in kW.
