How much beer is in that beer line?

[UpstateMike]

Ok, so I got bored, and I thought maybe I should do some practical math. So I was wondering, how much beer is in the beer line? Well, using our friend math, and the formula Volume = Pi * R Squared * Length, here's what I came up with.



I figured it out for a 10 foot line. Want to figure for your length? Divide by 10 and then multiply that by the length of your beer line in feet.

If I run a line from the basement 2 floors up to the kitchen 65'. If the beer is kept at 34*F how cold will the first pour be in a 20oz glass?

VERY interesting. I never thought to figure it out but kind of wondered now and then. When I bottle from my keg I always take a small glass and take a pull to sort of flush out the line with beer that sat. I realize that is silly but then again, I drink it so there is no real waste.

Wow! That is bored!

Purple, because aliens don't wear hats.

If you use 3/16" line, the first 12oz of your beer will have been sitting in the lines for however long since your last pour. Which doesn't sound great...

Great chart, BTW!

Good job on the math! I only checked the first one. Only reason I did is because I have a associates degree in math and 3/16 line.

And here I was being lazy and just reading the description on the line I bought:

Technical Specifications: 3/16" line provides 2.2 lbs of restriction per foot. Ideally pounds of resistance should equal pounds of applied pressure. 3/16" line holds 1/6 of an ounce per foot. PVC Free. 7/16" OD

Now to my horror I find I've actually had .17 oz more in those 10ft lines than I thought!

Damn kids these days, with their highfalutin fancy shmancy tubing with the writing on it. Surprised you didn't pull out your eye-fone and say "Siri, how much beer is in my lines?"

LOLZ, just kiddin'!

HA! nope, no eye phone in this house. As a matter of fact thanks Hello, I didn't get the reference at first.
I just pulled out my trusty old-lady reading glasses and read that there fine print for myself.
