How can I calculate flow rate for leaking pressure vessel during maintenance?

[QUOTE="Rx7man, post: 5473187, member: 583059"] Easiest way I could think of is to bleed off as much as necessary after 1 minute into some container until you're back down to your original (10 psi) reading.. Perhaps do it a couple times and average it? Mainline pressure is pretty irrelevant because the flow difference between a 490 psi leak and a 500 psi leak is negligible. It's really hard to solve this without knowing how much air is in the system, or mixed in with the crude.. a big air bubble in the system could DRASTICALLY change how 'compressible' the whole system is, as the air is easy to compress... With no air at all, a small leak will raise pressure quickly, while with air (lets say 50L of air space), the same leak may not show hardly at all I'm no expert, but I don't think there's a 'neat', reliable mathematical solution to this.. Bleeding off to maintain a given pressure and measuring is about the most reliable way, if it's feasible. [/QUOTE]
