Asteady-flow carnot refrigeration cycle uses refrigerant-134a as the working fluid. the refrigerant changes from saturated vapor to saturated liquid at 400c in the condenser as it rejects heat. the evaporator pressure is 100 kpa. show the cycle on a t-s diagram relative to saturation lines, and determine

(a) the coefficient of performance.
(b) the amount of heat absorbed from the refrigerated space.
(c) the network input.

Amass of 3 kg of saturated liquid-vapor mixture of water is contained in a piston-cylinder device at 150 kpa. initially, 1 kg of the water is in the liquid phase and the rest is in the vapor phase. heat is now transferred to the water, and the piston, which is resting on a set of stops, starts moving when the pressure inside reaches 500 kpa. heat transfer continues until the total volume increases by 20 percent. determine (a)-the initial and final temperatures, (b)-the mass of liquid water when the piston first starts moving, and (c)-the work done during this process. d)-show the process on a p-v diagram. you don't need to indicate p& v values, but clearly indicate where all states are located in the phase diagram.
