Velocity Calculation
Velocity Calculation
(OP)
I have a 5/16" I.D. tube with (27) 1/32 holes equally spaced along the entire length. It is used to move plastic cups. What I need to determine (roughly) is the velocity of air coming out of each hole with approx. 100psi shop air being applied to the tube.
Actual number or just a formula is what I need.
Thanks in advance,
Jason

RE: Velocity Calculation
Problem is that with holes that small, you really can't disregard the pressure drop through the pipe walls (if you could, then the air stream out of the holes would be really noisy at sonic velocity). I don't have an equation that describes pressure drop over a distance that short.
