Unformatted text preview: MPa. Some steam is extracted at this pressure to heat the feedwater in a feedwater heater. The rest of the steam is reheated to 500°C and is expanded in the low-pressure turbine to the condenser pressure of 10 kPa. Assume that the water leaves the heater at the condensation temperature of the extracted steam and that the extracted steam leaves the heater as a saturated liquid and is pumped to the line carrying the feedwater. Determine (a) the mass flow rate of steam through the boiler and (b) the thermal efficiency of the cycle....
