3. Figure P8.78 shows a vapor power cycle that provides process heat and produces power. The steam generator produces vapor at 500 lbf/in2, 800°F, at a rate of 8x104 Ib/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.* and passes through a trap before entering the condenser at 10 lbf/in.2 Saturated liquid exits the condenser at 10 lbf/in.2...

Water is the working fluid in a Rankine cycle. Steam exits the steam generator at 1500 lbf/in.2 and 1100°F. Due to heat transfer and frictional effects in the line connecting the steam generator and turbine, the pressure and temperature at the turbine inlet are reduced to 1400 lbf/in.2 and 1000°F, respectively. Both the turbine and pump have isentropic efficiencies of 95%. Pressure at the condenser inlet is 2 lbf/ in. 2, but due to frictional effects the condensate exits the...

WWVUU moressar Q-1 A power plant operates on a regenerative vapor power cycle with one closed feedwater heater. Steam (water vapor) enters the first turbine stage at 120 bar, 520°C and expands to 10 bar, where some of the steam is extracted and diverted to a closed feedwater heater. Condensate exiting the feedwater heater as saturated liquid at 10 bar (State 7) passes through a trap (valve) into the condenser. The feedwater exits the heater at 120 bar with a...

Consider a reheat-regenerative vapor power cycle with two feedwater heaters, a closed feedwater heater and an open feedwater heater. Steam enters the first turbine at 8.0 MPa, 500°C and expands to 0.8 MPa. The steam is reheated to 500°C before entering the second turbine, where it expands to the condenser pressure of 10 kPa. Steam is extracted from the first turbine at 2 MPa and fed to the closed feedwater heater. Feedwater leaves the closed heater at 200°C and 8.0...
