Delivery Velocity to Reservoir
Delivery Velocity to Reservoir
(OP)
Hi,
I would like to know if there are some rule of thumbs for delivery velocity in a fluid (jet fuel) line that is pumped to a reservoir. I found a rule of thumb of 10-15 ft/s for oil return lines, which i believe would be my situation. If anyone happens to have more useful information, please let me know.
Thank you,
Gabriel

RE: Delivery Velocity to Reservoir
Rules of thumb are almost always one-dimensional--you have a maximum flow rate of hydrocarbon liquid into the top of a tank of 3 ft/s to limit static. If your dimension was "erosion" then the number would be different (maybe 100 / rho^0.5), if it was trying to limit wasted pump hp it would be different yet.
Trying to do Engineering design with an inappropriate "Rule" will often end badly (use the erosion number above to put a 0.72 SG jet fuel into the top of a tank and the 17 ft/s allowed could easily blow up the tank).
