1. 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.

2. A power plant has a condenser temperature of 45?C, a maximum pressure of 5 MPa, and a boiler exit temperature of 900?C. It has one open FWH operating at 1 MPa. Find the fraction of extraction steam flow, the two specific pump work inputs, and the turbine work per unit mass flow in the boiler.
