Steam enters a turbine operating at steady state at 600°F and 200 lbf/in^2 with a velocity of 80 ft/s and leaves as saturated vapor at 5 lbf/in^2 with a velocity of 300 ft/s. The power developed by the turbine is 200 horsepower.

At steady state, a reversible heat pump cycle discharges energy at the rate to a hot reservoir at temperature TH, while receiving energy at the rate from a cold reservoir at temperature TC.
