How many gallons in a 2 inch pipe 1 foot long?

Answer 1

Do the math:

Volume of a Cylinder: pi * height (in cm or in) * Radius Squared.

so, 3.14 * 24 (The radius of a 2" pipe is 1, and that squared is STILL 1)

The answer to that will give you CUBIC inches. 231 c.i = 1 Gallon.

I know the volume of a cylinder.

I was asking what the in3 (in cubed) meant in

1 Gallon = 231 in3

So, i guess if I wanted 1 FOOT, then 1.632 / 10 would equal .1632 gallons
