Four hundred kg/h of Steam from a low pressure turbine at 12.5 atm. and 250 C goes into a feed water heater which preheats the water entering the economizer in a boiler. The steam is comes out of the feed water at 200 C. The water at a flow rate of 500 kg/h enters the feed water heater at 20C. Calculate the feed water exit temperature.
