I'm working on a problem and need to find quality, mass, and pressure. I'm given a temperature (2°C), a volume (1200m^3), and a percent volume occupation (1% saturated liquid). Is it "legal" to use the saturated liquid tables, at 2°C, to find the volume or pressure (I forget which one we were discussing) and THEN move on to the correct saturated mixture table? Basically, given a temperature, volume, and percent volume, how would one find the quality and pressure. it's ammonia by the way, but that's not important right now. Figuring out how to find the right things is where we're at.
