CO2 Formula help

  1. Apr 18, 2008 #1
    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.

    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

    What I was asking above was vapor pressure. Can anyone help with a formula to calculate the vapor pressure in CO2 (or anything for that matter)?
