12g co2 psi?

Unread postAuthor: Marffy » Mon Nov 23, 2009 11:18 pm

I've searched everywhere for finding out how much psi is in a 12g co2 cartridge but i cant seem to find out how much psi. How much psi is in one?



I posted in this part of the forum because it's a pneumatic question and ill be using the co2 for a cannon.(i say this so you know i'm in the right part of the forum)

Typically around 800-900 psi. If you feed it into a chamber:

The following is a chart outlining the chamber size (in cubic inches) vs. pressure in (pounds per square inch) using a 12 gram CO2 cartridge:

Chamber Size (ci) Chamber Pressure (PSI)
10 420
20 210
30 140
40 105
50 84
60 70
70 60
80 53
90 47
100 42

Find Davidvaini's CO2 calculator. It'll work out the pressure you'll get from any size CO2 cartridge into any basic chamber dimensions at any temperature.

I didn't spend an evening helping him write it so it didn't get used.

I say this so you know i'm in the right part of the forum

Normally, it doesn't need qualifying.
