Steam enters a turbine steadily at 5 MPa and 500 C at a rate of 7 kg/s and exit at 0.5 MPa and 300 C. The steam is losing heat to the surrounding air at 100 kPa and 25 C at a rate of 300 kW, and the kinetic and potential energy changes are negligible. Determine: (a) The actual power output. (b) The maximum possible power output. (c) The second-law efficiency. (d) The exergy destroyed.
