I got bored and decided to try to make a force carbonation time chart for 40 psi.I used the set / forget pressure chart from kegerators.com and took the optimum volumes for a given temperature and used the referenced pressure to extrapolate that into a time frame for force carbing a 5 gallon corny at 40 psi.The numbers I came up with are all based on 14 days being the normal time frame to force carbonate using the set/forget method and a normal equalibrium pressure.This has been my experience, and the numbers on my chart seem to bear out what I've experienced force carbing at 40 psi.I also based my numbers on a linear increase as far as time / pressure / temperature....and made no adjustments for beer style.If anyone has any suggestions on improving or making the data more accurate, I wouldn't mind updating this to make it more accurate / useful....the math used was basically to take a given temp say 40 deg. f...find the optimum carb volumes from the kegerators.com chart (2.39 volumes)....find the pressure for that volume on the chart (11 psi)....multiply 11 psi x 14 (days) = 154...divide 154 by 40 (psi) = 3.85 (days to reach 2.39 volumes)....then 2.39 divided by 3.85 = .621 volumes per day......then just multiply .621 by a given number of days to see what the carb level will be at 40 psi .
