A turbine at a power plant receives steam from the boiler at a temperature of 700°F and pressure of 1000 psia. The steam leaves at a pressure of 3 psia and a quality of 95%. There is heat transfer to the surroundings (which are at 77°F) of 60 BTU/s and the power output is 500 BTU/s. Required:
Find work done by turbine.
