Please Check my Math, Balancing draft beer system

[GeoXP]

I've posted this on a couple other forums so please forgive me if you've seen it already...

So I just finished up my new Keezer on Monday. I'm carbing a couple kegs now. I did some research and it seems that my system will be balanced at 15psi

I have 5 feet of 3/16" beer line from the keg and I have almost exactly a 3' rise from the center of the kegs to the faucets.

Assuming the standard flow resistance of 2.7psi per foot of beer line, and I'm told you need to add 0.5 psi for every foot of vertical rise from the center of the keg to the faucet, my pressure should equal

(5 X 2.7) + (3 X 0.5) or 13.5 + 1.5 = 15

Sound right so far?

Also, I don't want my beer to be too over-carbed, so I'm setting my ales at about 45 degrees in the keezer. At 15PSI for that temp I should be able to get about 2.51 volumes of CO2 for my carbonation.

For most beers would that be an acceptable amount? I currently have two Pale Ale variations in there right now.


Thanks to all!!

The math looks correct, but....
Temperature will probably be an issue for you, 38 degrees is the ideal temperature. for every degree above 38, internal keg pressure (domestic fizzies) goes up about 1/2 psi due to CO2 expanding. To compensate for 7 degrees (3.5 psi) would put you above 18 psi and into over carbonation land. Drop the temp and let the beer warm in the glass or shorten the 3/16 choker a foot.
