Thermo VLE problem with mathcad
The problem is not the actual solution of the problem - it is getting mathcad to produce the answers (all homework is required to be done in Mathcad for this class). See the mathcad file here.
So, I need to find 3 things - bubble pressure, y1 and y2. I have 3 equations - modified Rault (1 for each species) and y1 + y2=1. I put these in a solve block, tell mathcad to find the answers and... it turns red. The solve block is on the second page.
Can anyone point out what I'm doing wrong here? I run into trouble all the time with these Find functions. So far in this class I'm spending much more time trying to figure out Mathcad than I am Thermo.
