Steam enters an adiabatic turbine at 5 MPa and 700°C at a rate of 18.6 kg/s. The steam leaves the turbine at 50 kPa and 200°C. What is the rate of work produced by the turbine in MW? What is the rate of change of entropy of the steam during this process in kW/K? If the turbine is reversible and adiabatic and the steam leaves at 50 kPa, what is the rate of work produced by this turbine in MW? Ans: 19.02 MW, 12.01 kW/K, 23.87 MW
