    How do I calculate flow rate from pressure drop?

    A little more info on this. I'm trying to measure leakage through a seal, a press fit. I'm finding a lot of formulas using pipe diameters, but in this case my "pipe" is sealed with an imperfect seal, hence the leakage. Do I need to know the gap around the seal? I would assume that to be...

    How do I calculate flow rate from pressure drop?

    Hi. I have a digital manometer measuring pressure in units of inch h20. I'm trying to measure flow rate of air (in cc/min) over 60 seconds. I can record the pressure drop in inch h20 over that time period, how can I calculate the flow rate in cc/min? The manometer I'm using only has a...
