fluid velocities inside pipe before erosion occurs?
fluid velocities inside pipe before erosion occurs?
(OP)
Hi folks,
If I were to have a 2-7/8" carbon steel pipe with a 2.441" ID (cross sectional area of 1.812"), what is the maximum velocity I could have flowing through it?
As it stands, if I flow 7000 bpd through this pipe, the velocity would be 13.99 ft/sec.
Any help would be appreciated.
Thanks

for example see http://www.eng-tips.com/viewthread.cfm?qid=348061
your veleocity isn't particularly high unless you've got hard particles in and you'ev got elbows or you're going into a tee at right angles.
Max velocity is an art not a science.
My motto: Learn something new every day
Also: There's usually a good reason why everyone does it that way

Depending on the compositional grade of the tubing, the maximum design velocities will differ. You could pay for a higher grade of tubing to delay or prevent added erosion. Another consideration is once you have erosion, your friction factor is changed and alters your critical velocity to flow or lift.

Ve = C / √ pmixt
Ve = erosional velocity
C = empirical constant, 100 for continuous flow, 125 for intermittent service
pmixt = gas/liquid mixture density, lbm/ft3
