View Full Version : What pressure does co2 come out at?
I know it depends on the temp, etc so it there any equation I could use to figure it out? Or is there just some ballpark range on how much prssure it comes out at?
Just wondering, I've been fiddling with this air cannon I made and I haven't gotten a reg for it so co2 it just going straight in.

This from Glenn Palmer:
amount of liquid CO2 in a 20oz tank pressure
21 oz 1150 psi+
20 oz 950 psi
19 oz 875 psi
17 oz 825 psi
15 oz 815 psi
12 oz 810 psi
6 oz 805 psi
2 oz 800 psi

NOTE - palmers figures are for 72F - if the temp changes so does the pressure - higher for warmer - lower for colder - which is why a tank left in the sun will blow a burst disk.

I've seen it happen, it's not a pretty site...

I remember one time a long long while ago...when we had to bring multiple Co2 tanks onto the field to get us through a game....
My friend and I were waiting for the whistle to blow...when all of a sudden I heard a loud POP and WHOOSH sound. I look over at my friend to see that his extra 7-Ounce Co2 tank that was *strapped* into his 4+1 pack...has launched itself into the air above his head. It must have gotten 10-11 feet in the air, spun a few times, like a firework, and fell back to earth.
Eh those memories make me miss my ole PMI-3 (vm68)...

My dad's tank blew in the closet, freaked me out, couldn't figure out what that sound was.
There isn't any equation for this??? Tom?
