A quality of water within a piston-cylinder assembly executes a Carnot power cycle. During isothermal expansion, the water is heated from saturated liquid at 50 bar until it is a saturated vapor. The vapor then expands adiabatically to a pressure of 5 bar while doing 364.31 kJ/kg of work.
a. Sketch the cycle on p-v coordinates.b. Evaluate the heat transfer per unit mass and work per unit mass for each process in kJ/kg.c. Evaluate the thermal efficiency.
How many gallons of mercury (sg=13.54) would weight the same as 5 gallons of castor oil which has a specific weight of 56.69 pcf?
