A closed, rigid tank contains a two-phase liquid–vapor mixture of Refrigerant 22 initially at -20°C with a quality of 47.50%. Energy transfer by heat into the tank occurs until the refrigerant is at a final pressure of 6 bar.

a) Determine the final temperature, in °C.

b) If the final state is in the superheated vapor region, at what temperature, in °C, does the tank contain only saturated vapor?

A two-phase liquid–vapor mixture of Refrigerant 134a is contained in a 2-ft3, cylindrical storage tank at 100 lbf/in.2 Initially, saturated liquid occupies 1.6 ft3. The valve at the top of the tank develops a leak, allowing saturated vapor to escape slowly. Eventually, the volume of the liquid drops to 0.6 ft3. If the pressure in the tank remains constant, determine (a) the mass of refrigerant that has escaped, in lb, and (b) the heat transfer, in Btu. PLEASE USE THE...
