Backflow Pressure
Backflow Pressure
(OP)
Anyone have a good reference formula for calculating backflow pressure for a capsule like feature?...in other words, picture this: if you were to take a tylenol pill, cut it in half, and laser cut a quantity of 50 .004" diameter circles around the cylindrical face, how would one calculate the backflow pressure given a known flow rate?
Thanks!
Thanks!

The formula for orifice pressure drop is probably for holes thru a flat surface whereas you are talking about hole thru a cylindical surface meaning the holes are not of an area equal to 0.004" dia. if it were a flat surface. You could of course calculate the actual area and use it in any formula.
