    Calculating CFM from PSI and C.S.A.

    With this formula, are we supposed to assume that velocity is in seconds? Obviously, I do not know what the background and proofs behind this formula are. And in my ignorance, I can't feel comfortable assuming what the units of a variable are expressed in.

    Calculating CFM from PSI and C.S.A.

    I know this thread is very old. But as I was reading, I couldn't help but ask myself "What are the time units when referring to the velocity in the equation: velocity = sqrt (2*Pressure/density)?"

    How Can I Calculate Air Flow Rate and Velocity Through an Orifice?

    Thank you Rocket. There is some very useful information on that website. However, their formulas are only useful with the charts that they have for their own products. I'm still searching for a formula from which I can create a spreadsheet calculator where I can enter in the pressure and the...

    How Can I Calculate Air Flow Rate and Velocity Through an Orifice?

    I have been searching for formulas to determine the flow rate and velocity of air through an orifice at a given pressure differential. I need to know the flow rate to determine the CFM requirements of the compressor. And I need to determine the velocity to be able to accurately size the...
