Transcribed Image Text:

Steam at A kPa and B°C enters a steam turbine at a flow rate of C kg/s. The steam leaves the turbine as a saturated vapour at D °C. The turbine delivers E MW of power. The turbine is insulated, but not perfectly. The average temperature of the insulation on the outer surface of the turbine is F °C. The environment surrounding the turbine can be considered to be the dead state at 25°C, 100 kPa. Detemine; a) The exergy destruction rate in the turbine, b) The net exergy flow input, c) The exergy loss due to heat transfer.
