Answer to Question #231597 in Mechanical Engineering for Mukhalad

Question #231597

A refrigerator operates on the reversed Carnot cycle and uses water as the working

fluid. At the beginning of the isothermal expansion, the steam has an absolute

pressure of 1kPa and a quality of 7%; at the end of the isothermal expansion, the

steam is dry and saturated. At the end of heat rejection process the water is saturated

liquid. Firstly: Sketch the T‐s and P‐v diagrams for the cycle, and secondly: for one kg

of water, calculate: a) The steam pressure at beginning of the heat rejection process,

b) the net work per cycle, c) the COP of the cycle in two conditions: 1‐refrigeration

and 2‐heat pump
