Consider a regenerative cycle using steam as the working fluid. Steam leaves the boiler and enters the turbine at 4 MPa, 400°C. After expansion to 400 kPa, some of the steam is extracted from the turbine for the purpose of heating the feed water in an open feed water heater. The pressure in the feed water heater is 400 kPa and water leaving it is saturated liquid at 400 kPa. The steam not extracted expands to 10kPa. Determine the cycle efficiency.
