Q-3 (25 pts.) Steam flows steadily into a turbine with a mass flow rate of 26 kg/s and a negligible velocity at 6 MPa and 600C. The steam leaves the turbine at 0.5 MPa and 200C with a velocity of 180 m/s. The rate of work (power) done by the steam in the turbine is measured to be W-20 MW. If the elevation change between the turbine inlet and exit is negligible, determine a) (5p) Inlet and exit enthalpies b) (20p) rate of heat transfer associated with this process (heat loss from the turbine) considering the changes in enthalpy as well as kinetic and potential energies.
