Let's try it in REAL units!!
Volume equals length times cross section (pi x radius squared).
(lets do it in cm, as that will give us an answer in ml)
So for a 10cm diameter pipe, 1m long that's:
100cm x 3.142 x 5cm squared
=7855 cubic centimetres. Now 1000 CC = 1 litre (gotta love metric!). so one metre of 100mm pipe will hold 7.855 litres of whatever!
To find the volume of water in a pipe you need to know the diameter and the length of the pipe. The formula is pi x radius squared x the length in feet x 12 to get cubic inches didvide by 277.42 ( cubic inches in an imperial gallon ) = gallons in the pipe.
For example 4 inch diameter pipe 10 feet long holds 5.43 gallons of water.
3.14 x ( 2 x 2 ) x 10 x 12 = 1507.2 cubic inches / 277.42 = 5.43 gallons

To find the volume of water in a pipe in metric units, you can use the formula for the volume of a cylinder: V = πr^2h, where r is the radius of the pipe and h is the height of water inside the pipe. Make sure to convert all measurements to the appropriate metric units before plugging them into the formula.
calculate the volume in centimeters and then convert 1000 cubic centimeters to a liter. Liters Volume of a Pipe = Length Pipe(cent.) *PI*radius Pipe (cent.) squared/1000
The volume of water in a pipe can be calculated using the formula: volume = area x length. For a 22mm pipe, the area can be calculated using the formula for the area of a circle: πr^2, where r is the radius (11mm). The length of the pipe in this case is 1 meter. By substituting these values into the formula, you can calculate the volume of water in the pipe.
The volume of a pipe is proportional to the square of its diameter. Since the diameter of the 8-inch pipe is twice that of the 4-inch pipe, the 8-inch pipe can carry four times the volume of the 4-inch pipe.
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.
To calculate the volume of water in a pipe, you need to use the formula for the volume of a cylinder, which is V = πr^2h, where V is the volume, r is the radius, and h is the height (or length in this case) of the cylinder. In this case, the radius is half of the diameter, so the radius would be 2 inches. Converting the length to inches, we have h = 120 inches. Plugging these values into the formula, we get V = π(2^2)(120) = 480π cubic inches. This is approximately 1507.96 cubic inches of water in a 4-inch pipe that is 10 feet long.
The water capacity of two 500' water pipes will depend on the pipe diameter. Typically, water pipe capacity is measured in gallons per minute (GPM) or liters per minute. The larger the diameter of the pipe, the higher the water capacity it can handle.
