Answer the following statement true (T) or false (F)
A) How much shaft work is produced in the turbine (per kg of water?) B) What is the actual physical state of the material leaving the turbine? (If a superheated vapor, give its temperature, and if a liquid-vapor mixture, give its quality.) C) How much heat is removed in the condenser (per kg of water?) D) What is the overall thermal efficiency of the complete cycle? E) What is the Carnot efficiency of a heat engine operating with a heat source at T=350 ?C and a heat sink at T=25 ?C?
A ship is powered by a heat engine, which operates on the following cycle: • Sub-cooled liquid water at P=50 bar enters a boiler. The effluent from the boiler is steam at T=350 ?C and P=50 bar. • The steam enters a turbine that has an efficiency of 80%. The effluent from the turbine has P=1 bar. • The turbine effluent enters a condenser and is cooled into a saturated liquid at P=1 bar. • The liquid water is pumped up to P=50 bar and returned to the boiler as sub-cooled liquid.
