Water is the working fluid in an ideal (so compression and expansion processes are isentropic) regenerative rankine cycle with one closed feedwater heater. superheated vapor enters the turbine at 12mpa, 480°c, and the condenser pressure is 6 kpa. steam expands through the first-stage turbine where some is extracted and diverted to a closed feedwater heater at 0.7 mpa. condensate drains from the feedwater heater as saturated liquid at 0.7 mpa and is trapped into the condenser. the feedwater leaves the heater at 10 mpa and a temperature equal to the saturation temperature at 0.7 mpa. the flow rate of steam entering the first-stage turbine is 45 kg/s. determine the magnitude of the rate of heat transfer from the working fluid passing through the condenser to the cooling water, in mw.
