The engine on a steam ship runs on the Rankine cycle. The steam leaves the boiler at 20 bar and 350C. The turbine has an efficiency of 75% and an outlet pressure of 1 bar. The pressure changes in the boiler and condenser can be considered negligible, the liquid leaving the condenser is saturated and the liquid can be considered incompressible. a. Determine the operating temperature of the condenser. b. Determine the work produced in the turbine per unit mass. c. Determine the heat released by the condenser per unit mass. d. Determine the work consumed by the pump per unit mass. e. Determine the heat consumed by the boiler per unit mass. f. Determine the efficiency of this heat engine. g. Compute the efficiency of a Carnot cycle operating between the boiler and condenser temperatures and compare it to the efficiency of the Rankine cycle
