Extra Coursework
(OP)
Did anybody attend a college that teaches a course on Vacuum Systems or the theory and/or practice behind vacuum?

It's really really hard (if not impossible) to achieve a perfect vacuum because:
1. There will always be a leak - allowing the outside something into the space where there is supposed to be nothing.
Or
2. There is something in the space that is out-gasing something into the space that is supposed to have nothing.
Or often both 1 and 2 at the same time.
And
3. The faster you try to remove the something from the space that is supposed to have nothing, the faster 1 and 2 happen.
Regardless, attempting to remove the something from the space that is supposed to have nothing is still fluid mechanics.
I think that's all there is to it.

This is especially true in vertical flow. One client has a bunch of wells with 15-20 in Hg vacuum on the wellhead--traditional math predicts that flowing bottom hole pressure should be 75-100 psig while pressure bombs measure 3-5 psig flowing bottom hole pressure. The difference is the amount of water that evaporates--that number is treated as insignificant in Turner, Coleman, and Grey, but in these wells it is greater than liquid inflow and the flow up the wellbore is single phase.

It is a great course.

For information on the technology used (a a little bit of theory) You could check out some of the courses offered by the Society of Vacuum Coaters:

Specifically, Donald Mattox's guides are handy for an introduction to the technology:
