A 1.5-ft³rigid tank contains saturated refrigerant-134 at 170 psia. Initially, 20 percent of the volume is occupied by liquid and the rest by vapor. A valve at the top of the tank is now opened, and vapor is allowed to escape slowly from the tank. Heat is transferred to the refrigerant such that the pressure inside the tank remains constant. The valve is closed when the last drop of liquid in the tank is vaporized. Determine the total heat transfer for this process. R-134a, Sat. mixture P = 170 psia V = 1.5 ft³
