12 gram CO2 cartridges are used primarily as a portable way to provide pressurized gas to a pneumatic cannon. They cost roughly 1$ a peice, and are typically connected via an adapter, which can be purchased for about (I have very little clue. 10-20$?) Once empty, they are often used as projectiles - they have a nice mass, and are quite sturdy.
Here is a chart:
| 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 valve, use this equation, but note that the pressure can't go above the 800 psi vapor pressure og 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=101.7psi Your 41.3ci chamber will have a pressure of 101.7psi when filled with one 12g CO2 cartridge. Simple, eh?
