Yes, i did mean a sub-cooled liquid.
I think the problem is clear now, and i will spell it out for anyone else who stumbles upon this post.
The vapor fraction domain which is being examined is split into 3 parts which are cut by two asymptotes (which are functions of the maximum and minimum...
Introduction: This is a detailed question about a very specific part of PVT analysis. It involves a binary mixture whose vapor fraction does not seem physically possible to me, even though all of my analytical tools tell me that it is correct. So then:
I am approximating the Rachford-Rice...
