Question

Steam is generated in the boiler of a cogeneration plant at 10 MPa and 450C at a steady rate of 5 kg/s. In normal operation, steam expands in a turbine to a pressure of0.5 MPa and is then routed to the process heater, where it supplies the process heat. Steam leaves the process heater as a saturated liquid and is pumped to the boiler pressure. In this mode, no steam passes through the condenser, which operates at 20 kPa. Determine the h4 at the pump (after the process heater) outlet in kJ/kg.
