How many gallons of water in of 8 inch pipe 100 feet long?

Answer 1

You cant answer this unless you have proper measurements. Assuming that the pipe is a cylinder, using the equation V=(pi) r2 L

Where (pi) is 3.14159 and r is the radius of the pipe and L is the length of the pipe.

The question asks for Gallons, a unit of Volume. What is given is the length and width, used to find an area.

Answer 2

Assuming that the pipe is 1" in diameter on the inside (so, if it were a 1/8" thick pipe, the overall diameter would be 1.25"), then the volume would be approximately 8.16 gallons.

To get this, one would take the radius (1/2" in this case), multiply it by ∏, according to the formula Area of a circle = ∏r2. Take this and multiply it by 1200" (100'). This would be your volume in cubic inches. To go from there to gallons, use the conversion of 1gal = 231 cubic inches.

This will result in approximately 8.16 gallons.

Answer 3

1 gallon = 231 cubic inches

1 foot = 12 inches

100 feet = 1,200 inches

Volume of a cylinder = (pi) (Radius)2 (length)

Radius = 1/2 of diameter = 1/4 inch

Volume = (pi) (0.25)2 (1,200) = 235.62 cubic inches = 1.02 gallon (rounded)

That's the volume of the pipe. We have no way of knowing how much water

is in it. It could even be empty.

Answer 4

100 feet of 1" pipe holds about 4.1 gallons.

Answer 5

assuming 8in inner diameter and US Gallons:

pi * r^2 * length (all units must be the same)

pi * 4in^2 * 1200in = 60318.5789 cubic inches

60318.5789 = 261.12 Gallons

Answer 6

The capacity of 100-ft of 1.25-inch diameter pipe is 6.375 gallons. (rounded)

We have no way of knowing how much water is in it. Maybe it's empty.

Answer 7

One US gallon.

Answer 8

36.7 gallons or 4.9 cubic feet.
