A pipe 1 foot in diameter and 6 foot long will hold (pi x 0.52 x 6) cubic feet
Taking pi as 3.1416 we can rewrite the formula as 3.1416 x 0.25 x 6 = 4.7124 cubic feet.
A US gallon = 0.13368056 cubic feet - which would mean that the pipe held 4.7124 / 0.13368056 = 35.25 US gallons
An Imperial gallon = 0.16054365 cubic feet - which would mean that the pipe held 4.7124 / 0.16054365 = 29.35 Imperial gallons

To find the volume of water in the pipe, calculate the volume of a cylinder using the formula V = πr^2h, where r is the radius of the pipe and h is the length of the pipe (2600 feet). First convert 6 inches to feet (0.5 feet). Then plug in the values and calculate the volume.
A piece of pipe with a 6-inch inner diameter that's 700-ft long has a capacity
of 137.4 cubic feet, or 1,028.16 gallons.
We have no way of knowing how much water is in it. For all we know, it may
even be empty.
This pipe will hold 1,468.8 gallons of water.
A 1.5 inch (diameter) pipe that is 10 feet long can hold approximately 3.32 gallons of water. This calculation is based on the volume of a cylindrical pipe.
A 2.5 inch fire hose has a capacity of approximately 60 gallons per 100 ft. Therefore, a 50 ft hose would hold around 30 gallons of water.
The volume of a cylinder is (pi) x (radius)2 x ( length) .Radius is 1/2 of the diameter.Radius of a 3-inch pipe is 1.5 inches.1 foot = 12 inches1,000 feet = 12,000 inches1 gallon = 231 cubic inchesVolume = (pi) x (1.5)2 x (12,000) = 84,823 cubic inches = 367.2 gallons (rounded)
One acre inch of water is approximately equal to 27,154 cubic feet. This measurement is commonly used in agriculture and irrigation to determine the amount of water needed to cover one acre of land to a depth of one inch.
