Pipe volume in liters: how to calculate and what formulas are best to choose

How to calculate the volume of a pipe in liters of liquid passing through a pipe excites everyone who is faced with such a need. The need arises in the case of designing a new heating system, and the indicators themselves help determine the choice of equipment, the dimensions of the expansion tank. This indicator is also important when using a substance such as antifreeze, which is sold in several forms:

  • diluted;
  • concentrated.

In the first case, the liquid can withstand up to -65оС, the second type freezes already at -30оС. To determine the volume of a canister or bottle with a substance, it is important to know the volume of the coolant. So, with 70 liters of pipe volume, 35 liters of undiluted antifreeze will be required, which is enough to be diluted in a 1: 1 ratio, which in the end is equal to 70 liters.

The rows in the table above provide actual calculations for common pipe diameters that you can rely on.

Formula for calculating indicators

Accurate data can be obtained by measurements and calculations, for this you will need some tools:

  • calculator;
  • caliper;
  • ruler.

This short list of tools should be enough to get the parameters you need.

To calculate the pipe volume in liters, measure the pipe radius (R). It is either internal or external. The first allows you to determine the amount of liquid that fits inside the cylinder, that is, the internal volume of the pipe, its cubic capacity. The second is the size of the space occupied by the structure.

In addition, pipe diameter data (D) is required, for the calculation of which the formula is used: rx2.

You will also need to determine the circumference (L).

How to calculate the volume of a pipe in liters

This indicator is measured in cubic meters (m3), and to get the desired figure, you will have to first calculate the area of ​​the pipe. The exact value can only be obtained after calculating the cross-sectional area. For this, the formula S=Rxπ is used, where S is the desired area, R is the radius of the pipe, π is 3, 14159265. The resulting value is multiplied with the length of the pipeline.

The volume of the pipe in liters is found using the formula, and the required value is obtained from a single-level action and only two values. The formula itself is as follows: V=SxL, where V is the volume of the pipe, S is the cross-sectional area, L is the length indicator.

An example of calculating the volume of a pipe

Let's take a metal pipe with an inner diameter of 50 and an outer diameter of 54 mm and a length of 220 mm. To carry out calculations, you will need to insert into the formula for calculating the area of ​​\u200b\u200bthe circle the size of the outer cross member of the metal, in this case the pipethe area will be equal to: V=D1xD2xLxp=4, 319 liters. In this case, the volume of 1 m of the pipe will be 1.963 l, and the surface area will be 0.373 m2.

This formula is used to calculate the volume of a pipe of any diameter, regardless of what material was used during production. To determine the indicators of the volume of a pipeline consisting of several structural parts, the formula is calculated separately, writing out the volume of each section.

Features of calculations

When calculating, make sure that the units of measurement are expressed in the same way. Otherwise, you won't be able to get the correct number. For example, you need to multiply the diameter, expressed in meters, and the length, in centimeters. Better convert all values ​​to cm2. Otherwise, when using different units of measurement, you risk getting dubious data as a result, which does not correspond to reality and is quite distant from the real values.

If you work as an engineer and do this kind of work on a daily basis, you can program the calculator by setting constant values. For example, the number P multiplied by 2.

This contributes to faster work on finding the required value.

How to calculate pipe volume in liters

Modern technological capabilities make it possible to use special engineering and architectural programs, where certain parameters and standard values ​​​​are already prescribed in advance. All that is required from the user's side is to substituteadditional individual indicators measured in an apartment or house.

Pay attention! When arranging water-type systems, it is not necessary to carry out an accurate calculation, it is more needed in order to determine the exact amount of materials and not to waste. An approximate selection of the volume is enough.

Now you know how to find the volume of water in a pipe in liters, thanks to the simple formulas given in the article.
