3 inch (inside diameter) pipe = 0.25 feet. Radius = 0.125 ft
Cross section area = pi*(0.125 ft)2 = pi * 0.015625 ft2 . Multiply by 80 ft = pi * 1.25 cubic feet = 3.926990817 cubic feet x 7.480517578 (US gallons / cubic ft) = 29.37592384 US gallons.

The volume of water in a pipe depends on its length as well as its diameter. To calculate the volume of water in a 3-inch pipe, you would need to know the length of the pipe as well. Once you have that information, you could use the formula for the volume of a cylinder (πr^2h, where r is the radius of the pipe and h is the length of the pipe) to find the volume in cubic inches, which can then be converted to gallons.
If 3 inches is the pipe's diameter, then the answer depends on the pipe's length.
If 3 inches is the pipe's length, then the answer depends on the pipe's diameter.
This pipe will hold 1,468.8 gallons of water.
A 5-inch pipe will hold approximately 0.36 gallons of water per linear foot. This calculation is based on the formula for calculating the volume of a cylinder (V = πr^2h), where the radius (r) is half the diameter of the pipe (2.5 inches) and the height (h) is 1 foot.
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.
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)
