    Default Volume per foot of beer line?

    I'm trying to understand the cost benefits of line traps. To do so, I'd like to know how much beer by ounce is contained in each foot of beer line. If anyone knows, I'd like to know the figures for 1/4, 3/8 & 1/2 lines. I figure in my 30 feet of beer line, I gotta be losing at least 1-2 full pints everytime I do a keg change. Any thoughts?

    Some quick math say's

    1/4" = 1/3 oz. per foot
    3/8" = 3/4 oz. per foot
    1/2" = 1.3 oz. per foot

    You can always invest in FOBs to solve the waste problem. When you finish a keg off gas fills the FOB. A float valve in the FOB falls down and blocks off the line keeping the beer line completely filled. Thats way you don't waste a drop
    You just tap a new keg on, fill the FOB with beer and away you go pour pour pour.

    I believe that when he said "line traps", he was talking about FOBs

    Easy way to determine amount of beer lost with each keg change is to measure the amount of foam poured through the line before clear beer is poured. Foam is 1/4 beer, so if you through out 1 pitcher of foam it is equal to approx. 15 ounces of beer.

    figure it out do the math. what you're looking for is the volume of a cylinder which what a beer line is. formula would be pi r squared times the height or (length of the line)

    There's a chart on this link that tells you the volume of beer in a line, in ounces, per foot of line, citing various diameter lines.

    Sometimes when I reflect back on all the beer I drink I feel ashamed.
    Then I look into the glass and think about the workers in the brewery
    and all of their hopes and dreams. If I didn't drink this beer, they might
    be out of work and their dreams would be shattered. Then I say to myself,
    "It is better that I drink this beer and let their dreams come true than
    be selfish and worry about my liver."
