The figure below shows a vapor power cycle that provides process heat and produces power. The steam generator produces vapor at 500 lbf/in.², 800°F, at a rate of 8 x 105 lb/h. Eighty-eight percent of the steam expands through the turbine to 10 lbf/in.² and the remainder is directed to the heat exchanger. Saturated liquid exits the heat exchanger at 500 lbf/in.² and passes through a trap before entering the condenser at 10 lbf/in.² Saturated liquid exits the condenser at 10 lbf/in.² and is pumped to 500 lbf/in.² before entering the steam generator. The turbine and pump have isentropic efficiencies of 85% and 89%, respectively. For the process heat exchanger, assume the temperature at which heat transfer occurs is 465°F. Let To = 60°F.

The figure below shows a vapor power cycle that provides process heat and produces power. The steam generator produces vapor at 500 lbf/in.2, 800°F, at a rate of 8 x 104 lb/h. Eighty-eight percent of the steam expands through the turbine to 10 lbf/in.2 and the remainder is directed to the heat exchanger. Saturated liquid exits the heat exchanger at 500 lbf/in.2 and passes through a trap before entering the condenser at 10 lbf/in.2Saturated liquid exits the condenser at 10 lbf/in.2 and is pumped to 500 lbf/in.2 before entering the steam generator. The turbine and pump have isentropic efficiencies of 85% and 89%, respectively. For the process heat exchanger, assume the temperature at which heat transfer occurs is 465°F. Let T0 = 60°F, p0 = 14.7 lbf/in.2 Determine:(a) the magnitude of the process heat production rate, in Btu/h.(b) the magnitude of the rate of exergy output, in Btu/h, as net work.(c) the rate of exergy transfer, in Btu/h, to the working fluid passing through the steam…

1.10Water is the working fluid in a reheat-regenerative Rankine cycle with one closed feedwater heater and one open feedwater heater. Steam enters the turbine at 1400 lbf/in.2 and 1000°F and expands to 500 lbf/in.2, where some of the steam is extracted and diverted to the closed feedwater heater. Condensate exiting the closed feedwater heater as saturated liquid at 500 lbf/in.2 undergoes a throttling process to 120 lbf/in.2 as it passes through a trap into the open feedwater heater.The feedwater leaves the closed feedwater heater at 1400 lbf/in.2 and a temperature equal to the saturation temperature at 500 lbf/in.2 The remaining steam is reheated to 900°F before entering the second-stage turbine, where it expands to 120 lbf/in.2 Some of the steam is extracted and diverted to the open feedwater heater operating at 120 lbf/in.2 Saturated liquid exits the open feedwater heater at 120 lbf/in.2The remaining steam expands through the third-stage turbine to the condenser pressure of 3.5…
