A single-stage ideal regenerative steam cycle has a boiler pressure and temperature of 5000 kPa and 500 C, and a condensing pressure of 10 kPa. The extraction pressure is 500 kPa. If the regenerative heater is a closed heater with the condensate pumped into the line following the heater (TTD=7 C), find:

(ii) the work ratio

(iii) the thermal efficiency
