Air chamber fill times
Air chamber fill times
(OP)
I am looking for a simplified equation that I can use to estimate the time needed to fill a 1 cubic inch chamber from zero pressure to 100 PSI, using a solenoid valve with a Cv of .29, .9 or 1.4 and a supply of 120 PSI. Thanks

I'll assume air.
Cv = Q/(16.05 * SQRT((P1^2 - P2^2)/(SG * (T+460))))
Where:
Cv = valve sizing coeffecient
Q = flow in SCFM
P1 = upstream pressure in PSI
P2 = downstream pressure in PSI
SG = Specific Gravity
T = temperature in degrees F
0.29 = Q/(16.05 * SQRT((135^2 - 15^2)/(1 * (60+460))))
Neglecting all the stuff Israekk mentioned, isn't that like 1/100th of a second? I'll let you work it if you need more accuracy than that
