How to calculate the volume of the pipe in liters of fluid passing through the pipe, worries 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, sold in several forms:
In the first case, the liquid can withstand up to -65 Β° C, the second type freezes already at -30 Β° C. In order to determine the volume of the canister or bottle with the 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 dilute in a ratio of 1: 1, which in the end is 70 liters.
The lines of the table above provide real calculations of common pipe diameters that you can rely on.
Formula for calculating indicators
Accurate data can be obtained through measurements and calculations, for this you will need some tools:
- calculator;
- calipers;
- ruler.
This short list of tools will be enough to get the necessary parameters.
To calculate pipe volume in liters, measure pipe radius (R). It can be internal or external. The first allows you to determine the amount of fluid placed 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, data on the diameter of the pipes (D) will be required, for the calculation of which the formula is used: rx2.
We also need the definition of the circumference (L).
How to calculate the volume of the pipe in liters
This indicator is measured in cubic meters (m 3 ), and in order to get the desired figure, you have to first calculate the pipe area. The exact value can only be obtained after calculating the cross-sectional area. For this, the formula S = RxΟ is used, where S is the desired area, R is the radius of the pipe, Ο 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 desired 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.
Pipe volume calculation example
Take a metal pipe with an inner diameter of 50 and an outer 54 mm and a length of 220 mm. To carry out the calculations, it will be necessary to insert the size of the outer cross member of the metal in the formula for calculating the area of ββthe circle , in this case the pipe area will be equal to: V = D 1 xD 2 xLxp = 4.319 liters. The volume of 1 m of pipe will be 1.963 l, and the surface area of ββ0.373 m 2 .
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 volume indicators of a pipeline consisting of several structural parts, the formula is calculated separately, writing out the volume of each section.
Computing Features
When calculating, make sure that the units are expressed in the same way. Otherwise, you wonβt get the right number. For example, you need to multiply the diameter, expressed in meters, and the length - in centimeters. Better translate all the values ββin cm 2 . Otherwise, when using different units of measurement, you risk obtaining dubious data that do not correspond to reality and are sufficiently distant from the present values.
If you work as an engineer and perform such actions daily, the calculator can be programmed by setting constant values. For example, the number P times 2.
This contributes to faster work on finding the necessary value.
Modern technological capabilities represent the real use of special engineering and architectural programs, where individual parameters and standard values ββhave already been spelled out. All that is required on the part of the user is to substitute additional individual indicators measured in an apartment or house.
Note! 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 be wasted. Rough enough selection of volume.
Now you know how to find the volume of water in a pipe in liters, thanks to the simple formulas given in the article.
