Table for CO2 pressure Vs size of cylinder

[crofty83]

I have just got a CO2 cylinder and hooked it up to my reg.

Is there a chart/table somewhere that would tell me what pressure to expect it to have when full?

Cheers folks.

50 Bar or around 850 psi, if you prefer. The pressure remains constant until the cylinder is nearly empty and then drops rapidly.

There is some slight variation depending on ambient temperature.

Are you psychic dude. How did you know what size cylinder I have?

It is not dependant on cylinder size, CO2 liquefies under pressure, as long as there is liquid CO2 in the cylinder the pressure in the 'space' above the liquid will be around 50bar (800psi) depending on temperature. . . .once that liquid is used up the pressure in the space drops rapidly

Beat me to it....again :lol:

Awesome guys. Thanks :-)

BTW Aleman, did you get my PM?

Nope.

No need to be :-)
