Your answer is nothing more than smartmouth as the diameter is already given above in the question for those who can be bothered to read.
A foot long tube, six inches in diameter.
So the calculation for the person asking the question is:
12 inches x pi (3.142) x radius (3) squared.
= 339.12 cubic inches
The pipe would need to be 10 feet 10.8 inches long.
This pipe will hold 1,468.8 gallons of water.
It depends on how much each pipe can hold. And how long each pipe is.
The volume of water in a pipe can be calculated using the formula: V = πr^2h, where V is the volume, r is the radius of the pipe (which is half the diameter), and h is the length of the pipe. Given a 4-inch pipe, the radius is 2 inches, and converting to feet, it becomes 0.167 feet. Therefore, the volume of water in a 4-inch pipe that is 10 feet long is approximately 7.89 cubic feet.
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.
A two inch pipe can hold 0.1632 gallons per foot. It takes slightly over 6 feet of two inch pipe to hold one gallon of water.
The volume of water in 1,500 feet of six-inch pipe is: 294.52 cubic feet or 2,203.2 US gallons.
The capacity of a pipe with a 54 inch inner diameter and a length of 120000 inches is 1,099,306,101 cubic inches, approx = 636,173 cu feet. There may or may not be any water in the pipe!
5.5 gallons per 15 feet of 3-inch pipe.
A 72-inch pipe 16 feet long holds up to 3,384.1 US gallons of water.
You would need 2,451 feet of 2-inch pipe for 400 gallons.
This pipe will hold 23,500.7 gallons of water.
This pipe has a volume 437.4 gallons.
100 feet of 3-inch pipe holds 36.73 gallons of water.
The pipe would need to be 10 feet 10.8 inches long.
This pipe will hold 1,468.8 gallons of water.
61,101.8 gallons per 2,600 feet of 24" pipe.
