Steam enters the turbine of a cogeneration plant at 7.0MPA and 500C. Steam at flow rate of 10kg/sec is extracted from the turbine at 600kPa pressure for process heating. The remaining steam continues to expand to 10KPA. The recovered condensate are pumped back to the boiler. The mass flow rate of the steam that enters the turbine is 32kg/s. Calculate the cogeneration efficiency.
