- 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?arrow_forwardI need help on this assignment: Exhaust gases from the turbine of a simple Brayton cycle are quite hot and may be used for other thermal purposes. One proposed use is generating saturated steam at 110℃ from water at 30℃ in a boiler. This steam will be distributed to several buildings on a university campus for space heating. A Brayton cycle with a pressure ration of 6 is to be used for this purpose. Plot the following:(a) The mechanical power produced,(b) the flow rate of the produced steam,(c) the maximum cycle temperature, all as functions of the rate at which heat is added to the cycle.arrow_forwarduse perrys chem engg handbookarrow_forward
