Under normal operation, a dairy plant requires 4 kg/s of saturated steam at 2 MPa, which is extracted from the turbine of a cogeneration plant. Steam enters the turbine at 8 MPa and 500 ºC 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 feedwater at the constant pressure. The mixture is then pumped to the boiler pressure. Determine. (a) the rate of process heat supplied, (b) the net power output and utilization factor for this operating condition, (c) the maximum process heat that this cogeneration plant can supply, (d) the net power output when there is no need for process heat.

Please reference all tables you use. Thanks.
