There is 1.5 gallons per foot in 6" pipe and 2.59 gallons in 8" pipe, so I would think there should be about 2 gallons per foot in 7" pipe.
bob... 1.998 gallon Pi x R Sq x L (12") divided by 231 as there are 231 " in a gallon
(pie)2.14R^2 * L / 27 all must be in the same units (ft. is best)
you get a (cu ft) answer h20 is 7.5 gal per cu ft 7.48 gal per cubic foot which equils 1 fixture unit If your figuring inches you take Pi x R 2 x L divided by 231 as there are 231" in a gallon IF your figuring feet you take Pi x R sq x L x 7.48 as there are 7.48 gallon in a CUBIC foot
Volume of a cylinder = (pi) (radius)2 (length)
Radius = 1/2 diameter = 0.5 inch
1 foot = 12 inches
700 feet = 8,400 inches
231 cubic inches = 1 gallon
Volume = (pi) (0.5)2 (8,400) = 6,597.3 cubic inches = 28.56 gallons (rounded)
That's the volume of the pipe. I have no way to know how much water is in it.
It could even be empty.

182.8 gallons of water.
A three-inch diameter pipe one foot long holds 0.367 gallon.
0.1631168The value 0.1631168 is the number of US gallons per foot of 2" pipe. The number of gallons per foot of 4" pipe is 0.652798
One gallon of water equates to 231 cubic inches.There are 231 cubic inches in one gallon of water.
I will work with the assumption that you mean an 18 inch diameter pipe. The radius (r) is 9 inches and the length (l) is 12 inches per foot. The volume contained will be calculated by ∏r2l = ∏ x 92 x 12. If we use 3.1416 as the value of ∏, that gives us 3.1416 x 81 x 12, which works out at 3,053.6352 cubic inches of water. Now, an Imperial gallon and a US gallon are different - an Imperial gallon holds 277.42 cubic inches and a US gallon holds 231 cubic inches So in Imperial gallons the 12 inches of pipe holds 3,053.6352 / 277.42 = 11.0072 gallons and in US gallons it holds 3,053.6352 / 231 = 13.2192 gallons.

The volume of water in a 4-inch diameter, 1-foot section of pipe is 0.6528 gallons of water.

1 acre = 43560 sq.feet. 1 foot deep water over an acre is 43560 cubic feet, which is 325851.4 gallons in 1 foot deep. If it is 1 inch deep (1/12 foot) then it is 27154.3 gallons in 1 inch deep.
The capacity of the tubing is 94.6 Imperial gallons, or 113.6 US gallons. There need not be any water in it!
