Consider a steam power plant operating on the ideal regenerative Rankine cycle with one open feed water heater. Steam enters the turbine at 14 MPa, 610oC and is condensed in the condenser at a pressure of 12 kPa. Some steam leaves the turbine at a pressure of 1.2 MPa and enters the open feed water heater. Determine
(a) The thermal efficiency (ηth) of the cycle and
(b) The fraction of flow extracted where bleeding occurs.
