A steam turbine receives steam at a pressure of 1 MPa and a temperature of 300 degC. The steam leaves the turbine at a pressure of 15 kPa. The work output of the turbine is measured to be 600 kJ per kg of steam flowing through the turbine. a) Determine the isentropic efficiency of the turbine, and list any necessary assumptions.
