How long is your line?

I know this topic has been covered thoroughly, but I want more input. I want an extra long line for belgians. My lines are 3/16 ID, the tap is 8 inches above the center of the keg, and the temp of the kegerator is 38F. I want a high volume, around 3.5. I've seen all the links, but my calculation leads to non sensical results. I used this page: http://hbd.org/clubs/franklin/public_ht ... lance.html
Using the table, I need 21.7 psi for 3.5 volumes at 38F, so:
(21.7-(0.66*0.5)-1)/2.7=7.54 feet
My beer lines are already six feet long and they balance pretty well around 12 psi. I don't know how many volumes I'm getting with my six foot lines, but I'm guessing somewhere around 2.0. It doesn't seem reasonable to me that the extra 1.5 feet of line would let me increase the pressure from 12 to 21.7 psi. so what length line should I use? also, is that psi correct? I've heard people talking about 15-20 foot lines at 30 psi for belgians.

I serve my weizen, soda, and fizzy wine at 40F, 20psi, with about 10' of 3/8" high restriction line and wish I had a couple more feet on there.

Our temps are close, so would you say 13 maybe 14 feet of line would be a good approximation for 3.5ish volumes?

It's certainly a good place to start. I made a 4' long jumper so I can turn my regular 6' lines into 10' lines as needed. If you are going to do the same you might want a 6'of 8' jumper to add to that 6' line. That is a lot of line coiled up on top of the keg, though, so you might want to consider some other pressure reducing techniques.

You can add restriction with a couple of pieces of smooth 1x2 lumber about 6" long clamped on the line with a C-clamp. Hillbilly as hell but it works.

You can pull the convoluted mixing insert from resin/adhesive/caulk tubes and insert them in the tubing to add restriction.

There are mesh looking SS inserts that go inbetween the QD and the line. These are sold to add restriction so you pour with a faucet attached right to the QD. You might be able to use one of these with a regular line and get the right restriction. They are kind of pricey though.

If you are really feeling super deluxe get one of those faucets that have an adjustable restrictor built right into them. I don't know how much range they have, but it might be enough for you. I never checked into them because they are way out of my budget!

thanks for all the other options, never considered any of them. the extra line length doesn't bother me so I'm just gonna get a jumper. can't wait to carb my dubbels that should be about done conditioning.
