7.14 A steam cogeneration plant can operate in two modes. On the first one, all the steam extracted from the turbine at 500 kPa passes through the process heater and no steam flows through the condenser. The second method is to rout some of the steam through the process heater (60%) and the remaining through the condenser. Assume that the exit from the process heater is saturated liquid. Calculate the power output of the turbine (in KW) and the heat duty of the process heater (in KW) for both modes of operation.
