![4. (a)
Steam enters a turbine steadily at 5MPa and 550°C at a rate of 6.25 kg/s and exits at 0.2
MPa and 150°C, (Fig. below). The steam is losing heat to the surrounding air at 100 kPa and 25°C at a
rate of 480 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, and (e) the exergy of the steam at the inlet conditions.
