Oil companies invest money in research (sometimes!) and this leads people that are not in the field with a lot of questions. Also some problems that happens are though and not easy to explain to students - things that look very simple can be very difficult in the field, with explosive atmospheres, harsh work conditions, precision requirements.
So, to sum it up, I saw no oil-engineering tag. And got curious if it was ok to post related questions here - there is drilling, measuring, and lots of things that involves engineers.
An example question below:
Imagine a cylindrical vertical steel tank, filled with liquid. In a big tank, the pressure the liquid exerts on the tank is enough to cause a displacement on the steel walls, making the tank "less cylindrical". Which is the most accurate model to analytically calculate the wall displacement as a function of height - fixing liquid fill level?
(also if you have the answer to the above question I can ask on the NOTmeta)
