How much water volume does a 2.79mm hose carry per foot of hose?

Answer 1

Volume of a cylinder = (pi) x (radius)2 x (length)

Radius = half of the diameter = 1.395 mm

1 foot = 304.8 mm

Volume = (pi) x (1.395)2 x (304.8) = 1,863.43 cubic millimeters per foot.

That's about 2,031 feet of hose to hold 1 gallon of fluid ... 2.79mm is an awfully skinny hose.
