V = Velocity in feet/sec

C = Orifice Coefficient = .95

P = Pressure differential = 130psi (150psi being released into 30psi)

A = Orifice area in inches squared = The orifice sizes will be in the range of .055" to .157" Diameter.

T = Air temperature = 70 degrees F.

I don't need an elegant formula, but if other variables are needed, use:

W = Mass of Air = Assuming .075 lbs/ft

Atmospheric Pressure will not be a factor in this application
