An ideal cogeneration steam plant is to generate power and 9400 kJ/s of process heat. Steam enters the turbine from the boller at 7 MPa and 500°C. One-fourth of the steam is extracted from the turbine at 600 kPa pressure for process heating. The remainder of the steam continues to expand and exhausts to the condenser at 10 kPa. The steam extracted for the process heater is condensed in the heater and mixed with the feedwater at 600 kPa. The mixture is pumped to the boiler pressure of 7 MPa.

Consider a reheat-regenerative vapor power cycle with two feedwater heaters, a closed feedwater heater and an open feedwater heater. Steam enters the first turbine at 8000 kPa and 480oC and expands to 700 kPa. The steam is reheated to 440oC before entering the second turbine, where it expands to the condenser pressure of 8 kPa. Steam is extracted from the first turbine at 2000 kPa and fed to the closed feedwater heater. The feedwater leaves the closed heater at 205oC and 8000 kPa and enters the boiler to complete the cycle. The condensate from the closed feedwater heater is throttled into the open feedwater heater. Steam extracted from the second turbine at 300 kPa is also fed into the open feedwater heater, which operates at 300 kPa. The stream exiting the open feedwater heater is saturated liquid at 300 kPa. The net power output of the cycle is 100 MW. If the working fluid experiences no irreversibilities as it passes through the turbines and pumps, determine: (a) mass flowrate of…
