Hey everyone,
First off, if you don't like math your eyes will probably glaze reading this. Sorry. This is just a fun thought I had. (My idea of fun is somewhat questionable at times.)
I am trying to figure out force carbing from a mathematical angle and wondered if any of you mathy folks, such as myself, have ever thought about it or has someone else already done this.
Right now I am starting basic and trying to see if this works.
Anecdotally it seems that when people keg and pressurize at their serving pressure it takes approximately 2 weeks to get the carbonation to equalize. That is 14 days X 24 hours = 336 hours.
Now let's say you factor in your pressure.
335 * 10 = 3360
Let's call that PSI hours.
So without taking anything else into consideration it takes 3360 psi hours to carbonate a keg to roughly it's proper volume of CO2 at 10psi.
(I am assuming 38 degrees F for 2.4 vols of CO2.)
So now I want to really force carb.
If I carb at 30psi for 36 hours that equals 30 X 36 = 1080psi hours
If I then carb at 20psi for 24 hours thats 480 psi hours.
1080 + 480 = 1560 psi hours.
We need 3360 psi hours so 3360-1560 = 1800 psi hours left.
If I want to finish at 10 psi that would be 1800 / 10 = 180 hours or 7.5 days. So using this schedule you could properly carb your keg in about 10 days instead of 14.
Using that same math: 3360 / 30 / 24 = 4.7 days at 30 psi constant
OR
3360/60/24 = 2.333 days at 60 psi constant.
This is just "back of the napkin" math but the numbers don't look too wild.
What do all you math geeks think?
