Consider a power plant with water as the working fluid that operates on a Rankine cycle. It has a net power output of 40 MW. Superheated steam enters the turbine at 8 MPa and 600°C (h = 3642 kJ/kg; s = 7.0206 kJ/kg K) and is cooled in the condenser at a pressure of 10 kPa by running cooling water from a lake through the tubes of the condenser. The isentropic efficiency of the turbine is 85%. The pump has...

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...
