Consider a cogeneration plant. Steam enters the turbine at 8 MPa and 600oC. 20% of the steam is extracted before it enters the turbine and 60% of the steam is extracted from the turbine at 500 kPa for process heating . The remaining steam continues to expand to 6 kPa. Steam is then condensed at constant pressure and pumped to the boiler pressure of 8 MPa. Steam leaves the process heater as a saturated liquid at 500 kPa. The mass flow rate of steam through the boiler is 20kg/s. Determine
(a) The net power developed.
(b) The rate of process heat supply and
