He made it.
He made it.

i hope this is what you rae talking about if not well i'm new
12 gram CO2 cartridges are used primarily as a portable way to provide pressurized gas to a pneumatic cannon. They cost roughly $0.50 a peice, and are typically connected via an adapter, which can be purchased for about $10 USD. Once empty, they are often used as projectiles - they have a high mass, are quite sturdy, and fit in 3/4" SCH. 40 PVC.
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
To calculate the pressure for any non-given value, use this equation, but note that the pressure can't go above 800 PSI (the vapor pressure of CO2).
4200/Chamber Volume In ci=Chamber Pressure in psi -OR- 4200/CV=CP For example: You have a chamber volume of 41.3ci. So it can be said that 4200/41.3=CP 4200/41.3 is equal to 101.6949152542373 For simplicity's sake we will round this to 101.7 This means that CP=101.7 PSI Your 41.3ci chamber will have a pressure of 101.7 PSI when filled with one 12g CO2 cartridge.
