Steam enters an adiabatic turbine operating at steady state with an enthalpy of 3251.0 kj/kg and leaves as a saturated mixture at 15 kPa with quality (dryness friction) 0.9. The enthalpies of the saturated liquid and vapour at 15 kPa are hf = 225.94 kj/kg and hg = 2598.3 kj/kg respectively. The mass flow rate of stream is 10 kg/s. Kinetic and potential energy changes are negligible. The power output of the turbine (in MW) is
