Velocity pressure -> Velocity FPM
Velocity pressure -> Velocity FPM

Perhaps this is already available, but if it is, I wasn't able to find this conversion:
Velocity pressures for different velocities. This would be a direct conversion from velocity pressure (in inches of water), to velocity (in feet per minute).
This is used, among other things, to measure air speed in pneumatic "material conveying" systems.
I have a table which I could submit, if necessary! Thanks for your time...

could this be used to convert PSI to velocity (fps) ?

:D
The pressure (differential) is p. The velocity in feet/second is v. The mass of air is approximately 0.002378 slugs.
v = sqrt[2*p/0.002378]
This is Bernoulli's Equation Solved with a constant density (greek letter rho, which looks like a p in most physics books). The p above, the pressure, is the difference between a reference undisturbed air and the moving air.
Good Luck
