backflow pressure
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!
this may not be the best forum for this question.  maybe
thanks kenat...i posted it under "other topics"...
regards,
italzo
