After a big mistake in this PF, I try to post my question here, hoping it is ok.
I'm looking for a more "simple" relation than Darcy's law.
I try to determinate what is the relation between air speed and differential pressure in a tube where there is a restrictor.
A kind of relation like V=kP, where V in m/s and P in Pa or mBar and k a constant.
I do not want to try experimentation to determine this relation, I'm looking for theoretical relation to calculate air speed with only a differential manometer with the + connected before the restrictor and the - after it.
In the Darcy's law, there is too much parameters I can't know.
Thank you in advance for your help, and rather impatient to read you.
