Question:
Steam enters a turbine at 9 MPa, 600°C, and 60 m/s and leaves at 20 kPa and 90 m/s with a moisture content of 5 percent. The turbine is not adequately insulated, and it estimated that heat is lost from the turbine at a rate of 220 kW. The power output of the turbine is 4.5 MW. Assuming the surroundings to be at 25°C, determine
(a) The reversible power output of the turbine
(b) The exergy destroyed within the turbine
(c) The second-law efficiency of the turbine.
(d) Also, estimate the possible increase in the power output of the turbine if the turbine were perfectly insulated.
