12 gram CO2 cartridge

CO₂ cartriges are used primarily as a portable pressure scource. They are typicaly connected via an adapter. After being emptied, they are often shot at stuff - they have a nice mass, and are quite sturdy.

Here is a chart:

To calculate the pressure for any non-given valve, use this equation, but note that the pressure can't go above 800 psi, because that's CO2's vapor pressure.

4200/Chamber Volume In ci=Chamber Pressure -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 You're 41.3ci chamber will have a pressure of 101.7psi when filled with one 12g CO2 tank. Simple, eh?
