How about this plan: We'll explain how to solve the problem,

and then you go ahead and get the answer on your own.

The pipe is a cylinder.

The volume of the cylinder is: (pi) times (radius of the pipe)2 x (length of the pipe)

(Remember that the radius is 1/2 of the diameter.)

With that formula, you can find the volume of any length of pipe. You know the

diameter in inches, so the volume will be in cubic inches.

One gallon is exactly 231 cubic inches. Find what the length of the pipe has to be

in order to have a volume of 231 cubic inches.

Go to it ! You can do it !

How can you find the volume of a liquid in a 55 gallon drum in quarts from inches?

A 55 gallon drum is just a cylinder and, as such, the volume can be determined by the formula ¶r2h (Pi times radius squared times height). According to Wikipedia, standard 55 gallon drums are 22.5 inches in diameter and 33.5 inches high. The equation is thus 3.14 * 11.25^2 * 33.5. That comes out to 13313 cubic inches or 7.7 cubic feet.

How many gallons of water in a 2 inch pipe by 80 foot long?

Completely filled, (pi x radius squared x length in inches)/231 cu in per gallon = gallons = 13.06122449, if the inside diameter of the pipe is 2 inches. =========== Of course that assumes that the inside diameter is exactly 2 inches. For real pipes, the actual inside diameter of a pipe depends on the "schedule" of the pipe. For a "nominal" pipe diameter of 2 inches, the outside diameter will be 2.375 inches and the wall thickness could vary from .065 inches (schedule 5) to .343 inches (schedule 160) meaning that the actual inside diameter could vary from 2.245 inches to 1.689 inches.
