4 kg/s of saturated steam at 2 MPa, is-extracted from the turbine of acogeneration plant. Steam enters the turbine at8 MPa and 500°C at a rate of 11 kg/s and leaves-at 20 kPa. The extracted steam leaves the-process heater as a saturated liquid and mixes with the feed-water at constant pressure. The mixture is pumped to the boiler pressure.Assuming an isentropic efficiency of 88% for both the turbine and the pumps, determine the-utilization factor of the plant
