The engine on a steam ship runs on the Rankine cycle. The steam leaves the boiler at 20 bar and 350°C. 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, and the liquid leaving the condenser is saturated. A. Determine the operating temperature of the condenser, and compute the efficiency of a Carnot cycle operating between the boiler and condenser temperatures. B. Determine the actual efficiency of this Rankine cycle and compare it to the Carnot efficiency. C. When the Titanic was sinking, the Carpathia received the S.O.S. and immediately set course to attempt a rescue. The captain of the Carpathia ordered the hot water turned off in the passengers’ cabins (Lord, 1955). What effect do you expect this action had?
