I'm trying to figure a formula to determine what the pressure is in a CO2 bottle, while the liquid is still present. I am familiar with a CO2 Dynamics chart, but would like to know what the pressure would be at any temperature.(adsbygoogle = window.adsbygoogle || []).push({});

So far, what I have found through numerous hours of searching and calculating is this:

p = 4.51Te

where p is the pressure in psi

4.51 is a math constant

T is the temperature in Fahrenheit

and e is unknown (I believe it to be the expansion rate relative to the temperature but am not sure).

Any help would be appreciated
