A Carnot vapor refrigeration cycle operates between thermal reservoirs at 48C and 308C. The working fluid is saturated vapor at the end of the compression process and saturated liquid at the beginning of the expansion process. For (a) Refrigerant 134a, (b) propane, (c) water, (d) ammonia, (e) CO2 (using Fig. A-10), and (f) Refrigerant 410A (using Fig. A-11) as the working fluid, determine the operating pressures in the condenser and evaporator, in bar, and the coefficient of performance.

(11/09/2017) Model 2 To begin this sketch will be in inches 1. First start by turning off auto-dimensioning, and select top view. 2. Follow up by making two concentric circles, one 7 inches and the other one 10 inches, that have the center on the axis coordinates. 3. After that, make two lines one parallel to the x-axis and one that is perpendicular to the x axis that are 7 inches long and cross the center of the circles. 4. Then add lines that are 45° to the lines you already have until you have the smaller circle divided into 8 equal pieces. You can do this a faster way using the collinear function 5. After that convert all of the lines and the smaller circle int
