Consider a steam power plant that operates on the ideal
regenerative Rankine cycle with a closed feedwater heater as shown
in the figure. The plant maintains the turbine inlet at 3000 kPa
and 3508C; and operates the condenser at 20 kPa. Steam is extracted
at 1000 kPa to serve the closed feedwater heater, which discharges
into the condenser after being throttled to condenser pressure.
Calculate the work produced by the turbine, the work consumed by
the pump, and the heat...

a) A steam power plant operates on an ideal reheat-regenerative Rankine cycle. Steam enters the high-pressure turbine (HPT) at a pressure of 10 MPa and temperature of 550°C. The steam expands through the HPT stage to a pressure of 0.6 MPa. Some of the steam at the end of the expansion process in HPT is extracted for a regeneration process in a closed-type feedwater heater. The steam leaves the heater as a saturated liquid and then is throttled to the...
