There is a regenerative cycle that uses steam as the working fluid. Steam leaves the boiler and enters the turbine at 4 MPa and 400°C. After an expansion to 400 kPa, part of the steam is withdrawn from the turbine in order to heat the feedwater in an open feedwater heater (FWH). The pressure in the heater is 400 kPa, the water that leaves is a saturated liquid at 400 kPa, and the non-extracted steam expands at 10 kPa. Determine the efficiency of the cycle. the representation of the cycle is in the attached image.
