Q2/30 kg/s steam at 3 MPa, 300 °C expand isentropically in a turbine to a pressure of 100 kPa. If the heat transfer from the casing to surrounding air represent 1 percent of overall change of enthalpy of the steam. Calculate the power output of the turbine. Assume exist is 2 meter above the entry and the initial velocity of steam at inlet is 10m/s and exist velocity is 1 m/s.
