A 1.1-m3 rigid tank contains refrigerant-134a Chegg.com
WebA mass of 0.2 kg of saturated refrigerant-134a is contained in a piston-cylinder device at 200 kPa. Initially, 75 oercent of the mass is in the liquid phase. Now heat is transferred to the refrigerant at constant pressure until the cylinder contains vapor only. Show the process on a P-v P −v diagram with respect to saturation lines. WebSuva 134a HFC-134a is a haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane), but with less ozone depletion potential. R-134a has the … learnings in business plan
