A power plant operates on a regenerative vapor power cycle with one open feed water heater. Steam enters the first turbine stage at 11 MPa, 600oC and expands to 1 MPa, where some of the steam is extracted and diverted to the open feed water heater operating at 1 MPa. The remaining steam expands through the second turbine stage to a condenser pressure of 6 kPa. Saturated liquid exits the open feed water heater at 1 MPa. The net power output is 264 MW. Determine
(a) The fraction of flow extracted where bleeding occurs.
(b) The thermal efficiency (ηth) of the cycle,
(c) The mass flow rate into the first turbine stage and
