Preferred CO2 concentration calculation method?

[mashdar]

I have a couple of applications where I need to calculate dissolved CO2 from temperature and pressure, or some other form of the same equation.

I had assumed there was a "standard" method, but reading this paper, it sounds like there are a few.

Any opinions about what method to use for 32F-95F beer? Equations 4 sure are pretty, and I'm nothing if not empirical! Equation 7 is a simplified Henry's (with bounds, which is nice).

I scanned and then searched but found no incorporation of "time" in this paper's methodologies. That seems strange to me because it should be right behind temperature, pressure, and beverage chemistry in the list of factors that eventually lead to an end state...unless the reader is to assume as much time as needed to reach a stable state has passed...

Cheers!

Maybe to the point of equilibrium. But the time factor would be helpful, as it could take minutes or days.

Just a guess: Time would depend heavily on surface to volume ratio and fluid dynamics. It's probably unique for a particular vessel at a particular temperature, with strange break points as shape/temperature change.

A mostly full corny keg at 34-40F is a useful standard, though : )
