In a steam plant 100 kg/min of dry-saturated steam at 30 bar enters the turbine. After expanding isentropic ally the exhaust steam enters the condenser. The condenser pressure is maintained at 0.1 bar by the cooling water taken from a nearby river. Calculate the following: a. Dryness fraction of exhaust steam. b. Turbine work output. c. Work input to the feed pump.
