Extracted text: Consider a cogeneration system operating as shown in the figure below. Steam enters the first turbine stage at 6 MPa, 540°C. Between the first and second stages, y = 40% of the steam is extracted at 500 kPa and diverted to a process heating load of Oprocess = 5x 10° kJ/h. Condensate exits the process heat exchanger at 450 kPa with specific enthalpy of 589.13 kJ/kg and is mixed with liquid exiting the lower-pressure pump at 450 kPa. The entire flow is then pumped to the steam generator pressure. At the inlet to the steam generator the specific enthalpy is 469.91 kJ/kg. Saturated liquid at 60 kPa leaves the condenser. The turbine stages and the pumps operate with isentropic efficiencies of 82% and 88%, respectively.
