Assume that the power plant in Problem 9.45 has one closed FWH instead of the open FWH. The extraction flow out of the FWH is saturated liquid at 2033 kPa being dumped into the condenser, and the feed water is heated to 50?C. Find the extraction flow rate and the total turbine power output.

Problem 9.45

A Rankine cycle operating with ammonia is heated by some low-temperature source, so the highest T is 120?C at a pressure of 5000 kPa. Its low pressure is 1003 kPa, and it operates with one open FWH at 2033 kPa. The total flow rate is 5 kg/s. Find the extraction flow rate to the FWH, assuming its outlet state is saturated liquid at 2033 kPa. Find the total power to the two pumps.
