Steam enters an adiabatic turbine at 10 MPa and 800*c. It leaves the turbine at 800 kPa and 500*c. Neglecting Kinetic Energy find the "actual" work done by the turbine. If the exit temperature were not given but I said the turbine was adiabatic and reversible find the exit temperature to the nearest 10*c. What is the work for this condition? What is the isentropic efficiency for the "actual" operation?
