Air speed and differential pressure are there in relation?

  1. Jul 29, 2015 #1
    I am looking for a "simple" relation between differential pressure and air speed of a compressible fluid (air).
    I would like to calculate air speed in m/s in a a tube with a restrictor with only a differential pressure instrument, but not with experimentation, I'm looking for theorical formulation.

    Something like V= kP where V is in m/s, k a constant and P in Pa or mBar, I know there is the Darcy's law, but there is too much parameter that I could not measuring or knowing.

    Is my question is judicious ?
