Repeat problem 9-1-35 [OUU] , but replace the open feed water heater with closed feed water heater. Assume that the feed water leaves the heater at the condensation temperature of the extracted steam and that the extracted steam leaves the heater at state-10 as a saturated liquid before it is pumped to the line carrying the feed water. Determine
(a) The thermal efficiency (ηth) of the cycle and
(b) The mass flow rate of steam through the boiler.
