This pipe volume calculator **estimates the volume of a pipe as well as the mass of a liquid that flows through it**. This calculator is a helpful tool for everyone who needs to know the exact volume of water in a pipe. It will be helpful to you if you’re, designing an irrigation system for your garden.

Keep on reading to learn what a cylinder is and the volume of a pipe formula.

## Pipe volume calculator

Knowing the volume of a pipe might be useful for many reasons. It will benefit private homeowners, civil engineers, and construction workers. For example, you may want to know the water capacity of your in-home heating system or wonder if the pipe diameter you have chosen will be sufficient for refilling the garden pond.

This is the reason why we created the pipe volume calculator. This tool provides you with the volume of a specific pipe and the weight of the water (or other liquid) inside it. It is simple to use and effective. All you need to do is enter the pipe size – its `inner diameter`

and the `length`

. It doesn’t matter whether you use the metric or imperial system of units because you can freely switch between them using the drop-down list.

By default, the calculation of liquid weight is done for water (its density equals 997 kg/m³). If you need to do the calculations for other fluids, type in the density of your specific liquid.

Below, we prepared an explanation of the volume of a pipe formula and a step-by-step example of calculations to show you how to properly use the pipe volume calculator.

## Volume of a pipe – formula

By shape, a pipe is a hollow right cylinder. But what is a cylinder? We can see them around us every day. A cylinder is a solid with two bases, which are usually circular, and always congruent and parallel to each other. The ‘unrolled’ side of a cylinder creates a rectangle. The height of a cylinder is the distance between the bases (in the case of pipes, it is its length). The radius of a cylinder is the radius of its base. Keep in mind that when you have a cylinder, the diameter is a doubled radius. So, for calculations, you need to halve the diameter.
