Beer line volume calculation

[Freddy]

Hi All:
Either I'm having a problem with my calculus, but - I want to know how ro calculate the volume of beer in a given lenght of beer lines. Now, lets use an example:
Diameter of the beer line is 0.7 cm and the length (or h) is 12 cm Result:
3.142 X 72 X 12 = 1847.50 cm3
So, the volume of the line is 1847.50 cm3
Each cm3 holds 0.001 Liter of liquid, in our example it will be
1847.50 X 0.001 = 1.8475 Liter Is that correct?

Now, how is the oz/ft belew calculated?
The inner diameter of the tubing (ID) determines the liquid contents:
3/16” ID = 1/6 oz/ft
1/4” ID = 1/3 oz/ft
5/16” ID = 1/2 oz/ft
3/8” ID = 3/4 oz/ft

Also, at what point are we using 3/16"ID, 1/4"ID, 5/16"ID and 3/8" ID?????

I know is a lot of question, but I hope the our Micro Matic friends or anyone on the forum can help.

Cheers

I haven't used math since the invention of the internet. Thanks Al Gore!

where is the 72 coming from in your calculation?

cylinder volume =

Oddly enough, your end result is correct, but if you calculate 3.142 X 72 X 12, the answer is different than the one you have. I calculate 3.142 X 49 (mm) X 120 (mm) = 18,475 mm3 (1,847.5 cm3)

The info for line usage you're looking for is here - https://www.kegman.net/balance.html

1 cubic centimeter = 0.0338140227 US fluid ounces <-- I googled that.

Also, this conversion application I have on my phone tells me that 1 cm3 = .03381402270184 US fluid oz, if you want to be a bit more accurate.

where does 72 come from

7 squared = 49

still looking for an example to calculate the volume in oz

[cubby_swans]

Ahh, now I see. I understood 72 to be the number seventy-two.

still looking for an example to calculate the volume in oz

cm3 X .0338140227 = ounces

Or, if you're looking for a formula .0338140227 * () - assuming your solving using cm

Hi Cubby

here we go, where is my mistake in the calculus:

3/16 "ID = 1/6 oz per foot

How is that calculated in V=pieXr2Xh
cheers

How to calculate cubic inches to oz

1 cubic inch = 0.554112554 US fluid ounces


example:

5 ft of line = 60 in

ok...also V=(pi) * r^2 * h

so ID = 3/16 in. so radius (r) =3/32"

(pi) * (3/32)^2 * 60 =1.656699251 cubic inches

1.656699251 cubic inches =0.917997853 US fluid ounces **per 5 feet of 3/16" hose**
