You need to know two important dimensions of the pipe: the length and the inside radius (1/2 the inside diameter).
From there, you plug the dimensions in to this formula: radius2 x Pi (3.1416) x length. It is easiest if you ensure the dimensions are in the same format, such as feet or inches. Here is a sample:
The volume of a 50-foot long pipe with an inside diameter of three feet (1.5' foot radius) would be calculated as such:
Now there is the important final step of converting cubic feet to gallons of liquid. There are about 7.48 gallons in one cubic foot.
Since we know there are 353.43 cubic feet in the sample pipe above, we simply multiply 353.43 x 7.48 resulting in a maximum fluid volume of about 2,643.6564 gallons of water.

Since we know there are 1,413.72 cubic feet in the sample pipe above, we simply multiply 1,413.72 x 7.48 resulting in a maximum fluid volume of about 10,574.6256 gallons of water.
Assuming the pipeline is a cylinder, calculate the area of the circle (A=pi x r2) and multiply that number by the length of the pipe. Just make sure you use the same units. If you calculate the area using feet, then measure the length of the pipe in feet.
Using the inside radius and length of the pipe, apply this formula:
The volume of a pipe is calculated by multiplying Pi by the square of the radius by the length of the pipe.
