NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Steam is generated in the boiler of a cogeneration plant at 600 psia and 650°F at a rate of 42 lbm/s. The plant is to produce power while meeting the process steam requirements for a certain industrial application. One-third of the steam leaving the boiler is throttled to a pressure of 120 psia and is routed to the process heater. The rest of the steam is expanded in an isentropic turbine to a pressure of 120 psia and is also routed to the process heater. Steam leaves the process heater at 240°F. Neglect the pump work. A. Determine the net power produced. Use steam tables. The net power produced is ______Btu/s. B. Determine the rate of process heat supply. Use steam tables. The rate of process heat supply is ________Btu/s. C.Determine the utilization factor of this plant. The utilization factor of this plant is .
