If you have a fixed volume of refrigerant at a fixed temperature how do you find the percentage of liquid and the percentage of vapor? For example if I have a 1 ft³ of R-22 at 75°F (132.2psig), what volume is liquid and what volume is vapor? I know it's kind of an off the wall question, but it's something that's been bothering me, and I can't figure out how to calculate it. Vapor and liquid have different densities (right?) so that's my stumbling block. Thanks, Adam.
