Sometimes it is very important to accurately calculate the volume of water passing through the pipe. For example, when you need to design a new heating system. This raises the question: how to calculate the volume of a pipe? This indicator helps to choose the right equipment, for example, the size of the expansion tank. In addition, this indicator is very important when antifreeze is used. It is usually sold in several forms:

• Diluted;
• Undiluted.

The first type can withstand temperatures of 65 degrees. The second one will freeze at -30 degrees. To buy the right amount of antifreeze, you need to know the volume of coolant. In other words, if the volume of liquid is 70 liters, then you can purchase 35 liters of undiluted liquid. It is enough to dilute them, maintaining a proportion of 50–50, and you will get the same 70 liters.

To get accurate data, you need to prepare:

• Calculator;
• Calipers;
• Ruler.

First, the radius is measured, designated by the letter R. It can be:

• Internal;
• External.

The outer radius is necessary to determine the size of the space it will occupy.

To calculate, you need to know the pipe diameter data. It is denoted by the letter D and is calculated using the formula R x 2. The circumference is also determined. Denoted by the letter L.

To calculate the volume of a pipe, measured in cubic meters (m3), you must first calculate its area.

To obtain an accurate value, you must first calculate the cross-sectional area.
To do this, use the formula:

• S = R x Pi.
• The required area is S;
• Pipe radius – R;
• Pi number is 3.14159265.

The resulting value must be multiplied by the length of the pipeline.

How to find the volume of a pipe using the formula? You only need to know 2 values. The calculation formula itself has the following form:

• V = S x L
• Pipe volume – V;
• Sectional area – S;
• Length – L

For example, we have a metal pipe with a diameter of 0.5 meters and a length of two meters. To carry out the calculation, the size of the external cross member of the stainless metal is inserted into the formula for calculating the area of ​​the circle. The pipe area will be equal to;

S= (D/2) = 3.14 x (0.5/2) = 0.0625 sq. meters.

The final calculation formula will take the following form:

V = HS = 2 x 0.0625 = 0.125 cu. meters.

This formula calculates the volume of absolutely any pipe. And it doesn’t matter at all what material it is made of. If the pipeline has many components, using this formula, you can calculate separately the volume of each section.

When performing calculations, it is very important that the dimensions are expressed in the same units of measurement. The easiest way to calculate is if all values ​​are converted to square centimeters.

If you use different units of measurement, you can get very questionable results. They will be very far from the real values. When performing constant daily calculations, you can use the calculator's memory by setting a constant value. For example, Pi multiplied by two. This will help to calculate the volume of pipes of different diameters much faster.

Today, for calculations you can use ready-made computer programs, in which standard parameters are specified in advance. To perform the calculation, you will only need to enter additional variable values.

How to calculate cross-sectional area

If the pipe is round, the cross-sectional area should be calculated using the formula for the area of ​​a circle: S = π*R2. Where R is the radius (internal), π - 3.14. In total, you need to square the radius and multiply it by 3.14.
For example, the cross-sectional area of ​​a pipe with a diameter of 90 mm. We find the radius - 90 mm / 2 = 45 mm. In centimeters this is 4.5 cm. We square it: 4.5 * 4.5 = 2.025 cm2, substitute it into the formula S = 2 * 20.25 cm2 = 40.5 cm2.

The cross-sectional area of ​​a profiled product is calculated using the formula for the area of ​​a rectangle: S = a * b, where a and b are the lengths of the sides of the rectangle. If we consider the cross-section of the profile to be 40 x 50 mm, we get S = 40 mm * 50 mm = 2000 mm2 or 20 cm2 or 0.002 m2.

Calculation of the volume of water in the entire system

To determine such a parameter, it is necessary to substitute the value of the internal radius into the formula. However, a problem immediately appears. How to calculate the total volume of water in the pipe of the entire heating system, which includes:

• Radiators;
• Expansion tank;
• Heating boiler.

First, the volume of the radiator is calculated. To do this, its technical passport is opened and the volume values ​​of one section are written down. This parameter is multiplied by the number of sections in a particular battery. For example, one is equal to 1.5 liters.

When a bimetallic radiator is installed, this value is much lower. The amount of water in the boiler can be found in the device data sheet.

To determine the volume of the expansion tank, it is filled with the amount of liquid measured in advance.

The volume of pipes is determined very simply. The available data for one meter of a certain diameter simply needs to be multiplied by the length of the entire pipeline.

Note that in the global network and reference literature, you can see special tables. They show approximate product data. The error in the given data is quite small, so the values ​​given in the table can be safely used to calculate the volume of water.

It must be said that when calculating values, you need to take into account some characteristic differences. Metal pipes with a large diameter allow the amount of water to pass through, much less than the same polypropylene pipes.

The reason lies in the smoothness of the surface of the pipes. For steel products it is made with great roughness. PPR pipes do not have roughness on the inner walls. However, steel products have a larger volume of water than other pipes of the same cross-section. Therefore, to make sure that the calculation of the volume of water in the pipes is correct, you need to double-check all the data several times and confirm the result with an online calculator.

Internal volume of a linear meter of pipe in liters - table

The table shows the internal volume of a linear meter of pipe in liters. That is, how much water, antifreeze or other liquid (coolant) is needed to fill the pipeline. The internal diameter of pipes is taken from 4 to 1000 mm.

If you have a specific design or pipe, then the formula above shows how to calculate the exact data for the correct flow of water or other coolant.

Conclusion

To find the exact figure for the coolant consumption of your system, you will have to sit a little. Either search on the Internet or use the calculator that we recommend. Perhaps he can save you time.

If you have a water-type system, then you shouldn’t bother with precise selection of the volume. It is enough to estimate approximately. An accurate calculation is needed more in order not to buy too much and minimize costs. Since many people choose an expensive coolant.

Often people buy aquarium fish without thinking about what type of tank they need. When making such a purchase, it is very important to calculate the volume of the aquarium in liters. A lot depends on this characteristic: how many pets will live there, the volume of water, the amount of soil, etc. In fact, every adult knows how to calculate the volume of an aquarium; you just need to remember the knowledge acquired at school.

Why are calculations necessary?

It would seem that there is nothing simpler - buy a fish house, all the necessary components and place underwater inhabitants there. In fact, if the owner of the fish has not correctly calculated the capacity of the tank, her pets may not live in it for long.

• to understand what number of fish and plants will be optimal for a certain pet house;
• determine the amount of soil and fertilizers;
• Even when calculating the dosage of medications for pets, you need to know the aquarium data.

The fish house should be cozy for its inhabitants, then there will be no problems with the health of the pets.

How to make the calculation?

To understand how to find out the volume of an aquarium, you need to resort to the queen of all sciences - mathematics. Calculations will help determine how many liters will be needed to fill it, which heater and water filter to choose, and what species of fish can exist in it. Correct calculations are the key to the longevity of underwater inhabitants.

To calculate the volume of the aquarium, it is worth preparing special measuring instruments. The volume of an aquarium can be calculated using a calculator, tape measure and a pencil with a piece of paper. When you have prepared everything you need, you need to follow the instructions and remember what you went through at school:

• to calculate the volume of an aquarium that has the shape of a parallelogram (this is a standard type of product) you need to measure its outside length, depth and width;
• These three values ​​in the aquarium should be written down on a piece of paper, they will be useful for further calculations;
• The displacement of the tank using measured numbers is calculated by the formula: internal length × internal width × internal height;
• the question remains of how to calculate the internal quantities, for this you need to measure the wall of the tank, its thickness;
• the resulting figure must be multiplied by 2, then subtracted from the previously obtained external measurements, which will help obtain internal numbers;
• then we substitute the values ​​into the formula described above and convert the resulting value into cubic liters (1 m 3 = 1000 l) - this will be the volume of the aquarium or displacement.

There is an additional specific method for measuring the displacement of a tank. It's a little simpler than the previous one. It is necessary to make calculations using the formula: (H × D × D) × 0.001 (where H is height in cm, D is length in cm, D is depth in cm). This way you can subtract the liters correctly.

Based on the fact that one liter is 1000 times greater than one cubic centimeter, in order to obtain the volume in liters of some container measured in centimeters, you need to divide the result by 1000.

For example, the size of the container in centimeters is 25 x 25 x 10.

Calculator for calculating the volume of liquid in a rectangular container

Enter the dimensions in mm:

Instructions for an online calculator for calculating the volume in rectangular containers (such as an aquarium)

All values ​​are indicated in mm

H- Liquid level.

Y- The tank is high.

L- Length of the container.

X- The reservoir is wide.

This program calculates the volume of liquid in rectangular containers of various sizes; it will also help calculate the surface area of ​​the reservoir, free and total volume.

Based on the results of the calculation, you will learn:

• The total area of ​​the tank;
• Lateral surface area;
• Bottom area;
• Free volume;
• Amount of liquid;
• Capacity volume.

Technology for calculating the amount of liquid in tanks of various shapes

When a container has an irregular geometric shape (for example, in the form of a pyramid, parallelepiped, rectangle, etc.), it is necessary to first measure the internal linear dimensions and only then make calculations.

Calculating the volume of liquid in a small rectangular container can be done manually as follows. It is necessary to fill the entire tank with liquid to the brim. Then the volume of water in this case will become equal to the volume of the reservoir. Next, you should carefully drain all the water into separate containers. For example, in a special tank of the correct geometric shape or a measuring cylinder. Using the measuring scale you can visually determine the volume of your tank. To calculate the amount of liquid in a rectangular container, it is best for you to use our online program, which will quickly and accurately perform all calculations.

If the tank is large and it is impossible to measure the amount of liquid manually, then you can use the formula for the mass of a gas with a known molar mass. For example, the mass of nitrogen M = 0.028 kg/mol. These calculations are possible when the tank can be tightly closed (hermetically). Now, using a thermometer, we measure the temperature inside the tank, and the internal pressure with a pressure gauge. Temperature should be expressed in Kelvin and pressure in Pascals. The volume of internal gas can be calculated using the following formula (V=(m∙R∙T)/(M∙P)). That is, we multiply the gas mass (m) by its temperature (T) and gas constant (R). Next, the result obtained should be divided into gas pressure (P) and molar mass (M). The volume will be expressed in m³.

How to calculate and find out the volume of an aquarium by size yourself

Aquariums are glass vessels that are filled with clean water to a certain level. Many aquarium owners have repeatedly wondered how big their tank is and how the calculations can be done. The simplest and most reliable method is to use a tape measure and measure all the necessary parameters, which should be entered into the appropriate cells of our calculator, and you will immediately get the finished result.

However, there is another way to determine the volume of an aquarium, which involves a longer process, using a liter jar, gradually filling the entire container to the appropriate level.

The third method for calculating the volume of an aquarium is a special formula. We measure the depth of the tank, height and width in centimeters. For example, we got the following parameters: depth – 50 cm, height – 60 cm and width – 100 cm. According to these dimensions, the volume of the aquarium is calculated by the formula (V=X*Y*H) or 100x50x60=3000000 cm³. Next, we need to convert the resulting result into liters. To do this, multiply the finished value by 0.001. From here it follows - 0.001x3000000 centimeters, and we get that the volume of our tank will be 300 liters. We have calculated the full capacity of the container, then we need to calculate the actual water level.

Each aquarium is filled significantly lower than its actual height, in order to avoid overflow of water, and closed with a lid taking into account the screed. For example, when our aquarium is 60 centimeters high, then the glued ties will be located 3-5 centimeters lower. With our size of 60 centimeters, slightly less than 10% of the volume of the container falls on 5-centimeter ties. From here we can calculate the actual volume of 300 liters - 10% = 270 liters.

Important! You should subtract a few percent, taking into account the volume of the glass; the dimensions of the aquarium or any other container are taken from the outside (without taking into account the thickness of the glass).

From here the volume of our tank will be 260 liters.

There are several ways to calculate volume in liters. If you come across a liquid that is packaged in a bottle, then this volume is always indicated there. liters. However, there are containers on which the volume is indicated in cubic meters. From elementary school we know that 1 m^3 = 1000 liters. Accordingly, if you need to find the volume of any container in liters, you must multiply the given value in cubic meters by 1/1000:a (l) = b(m^3) * 0.001. Thus, you can calculate the volume in liters for a given volume, measured in m^3. This is a simple conversion from one SI unit to another. However, if you don’t yet know the volume, you will need to first find it in meters and then convert it to liters.

If you want to find out approximately how much water can be held in your existing aquarium, or if you are going to make a new one, then our volume calculator will help you quickly calculate aquarium volume rectangular or hexagonal shape.

How much will it cost to send your cargo to its destination? To answer this question, you need to know its volume in cubic meters, since transport companies most often indicate the cost of services in these units of measurement in their price lists.

Cardboard boxes are the most profitable and convenient type of packaging for most goods. When choosing corrugated packaging for your products, you need, first of all, to calculate the volume of boxes and order the required number of boxes so as not to transport air and not overpay for transport services.

If, as a result of the calculation, it turns out that you require corrugated packaging of individual sizes, our company MS-PAK will produce the required quantity to order. Let's look at how to correctly calculate the volume of a cardboard box.

Step-by-step calculation of the volume of a cardboard box

To calculate you need:

• Measure length A and width b, if the bottom of the box is square, then a=b;
• Measure height h as the distance from the bottom to the top flap of the box.

Formula for calculating the volume V in m 3 of a box with a rectangular or square base:

V=a*b*h
where a is the length of the base (m), b is the width of the base (m),
h – box height (m).

If the base of the box is not a rectangle, but a triangle, pentagon or hexagon, then the formula for calculating the volume will be:

V=S*h

where S is the area of ​​the base of the box, and h is its height.

Volume occupied by the workpiece (box)(taking into account wall thickness) is calculated for proper placement inside a vehicle or storage in a warehouse.
Formula for calculating the occupied volume:

Multiplying the obtained values, we get the volume of the box in cubic meters. To get the result in liters, you need to multiply the resulting value in m3 by 1000.

People who decide to engage in aquarium farming always face the question of how to calculate the volume of an aquarium in liters and find the optimal size of a decorative pond. At first glance, this may seem insignificant, but in fact the volume of the reservoir is very important for the normal life of fish. Some types of fish grow very quickly and require a large area. Therefore, the aquarist’s first priority is to choose the correct capacity of the tank.

Necessity of calculation

Of course, if you need to calculate the aquarium in liters, you can always seek help from a salesperson in a specialized store. The numbers indicated on the labels are approximate. In an aquarium there is an actual volume and a useful volume, which is always less than the first, because no one fills it to the brim (due to the lamps on the lid). In addition, a layer of soil is always poured onto the bottom, driftwood is laid and plants are populated.

You can measure the capacity along the inner and outer walls. These measurements will vary as the glass can be quite thick. The number of pets that can be placed in it depends on the size of the reservoir. And also their quantity depends on stress resistance, aggressiveness and size of fish and other inhabitants.

Pet stores have various options for pond care products: fertilizers, algae killers, water softeners, medications for fish. All these additives are used strictly based on the volume of water in the aquarium. Therefore, it is very important to independently calculate the value to determine the exact dose of the drug and avoid overdose.

Measuring a reservoir using formulas

To measure the capacity of a container, you will need simple tools. You need to prepare:

• Ruler. A construction tape measure or centimeter can also play this role.
• Calculator. With its help it will be possible to make a final and accurate calculation.

In addition, you will need school knowledge of physics and geometry. The easiest way to calculate the size of a cubic aquarium is. Before calculating the volume in liters you need to write down its dimensions in centimeters:

• A - length;
• B - width;
• C - height.

The resulting numbers need to be multiplied, and the result will be the volume in cubic centimeters. To convert them to liters, multiply the resulting result by 0.001, i.e. the calculation formula looks like this: A*B*C*0.001.

Cylinder-shaped containers are very popular today. They are used as marine reservoirs. To calculate the volume of an aquarium by size, you need to measure the radius of the base in centimeters (denoted as R) and the height of the container (H). The radius is squared, multiplied by Pi and the height. The result will be the volume value in cubic centimeters. Multiplying the value by 0.001 will give the volume of the container in liters. The formula looks like this: πR 2 *H*0.001.

The volume of a spherical reservoir is also can be calculated using a ready-made formula. You need to determine the radius of the ball (denoted as R), cube the resulting value, multiply by Pi and ¾. Next, you need to remember to convert the resulting value into liters. The formula for such a capacity is: πR 3 * 0.001 * ¾.

Other ways to determine displacement

Sometimes it is impossible to figure out how to calculate volume using a formula. You can divide a complex figure into simple ones, fit it into a cube or circle, calculate the volume by cutting off excess liters. Fortunately, there is an easy way to determine the value. For this you will need any measuring container. It is not difficult to guess that the measured volume of water that fills the aquarium is equal to its capacity.

In this way you can more accurately find out how many liters are in the aquarium. In this case, the volume of scenery, soil and instruments located in the water will be taken into account. The result obtained will give only the volume of water.

In order to find out the volume of the aquarium by size, you can use services on the Internet. There are various online calculators on the web to determine the displacement of an aquarium of any shape. You just need to specify the required parameters.

Choosing the Right Size

The biggest mistake for a beginner is buying a pond that is too small. An aquarium is an ecosystem in which plants that produce oxygen, fish that eat algae, and shrimp that eat leftover food grow. The larger the capacity of the aquarium, the more complete the ecosystem it contains.

For this reason, it is not recommended to buy a container smaller than 50 liters for your apartment - caring for it will be quite problematic. The best option would be a 100-liter reservoir. It is better to avoid round and intricate aquarium shapes, as the fish in them feel uncomfortable and are stressed. In addition, it is difficult to plant plants in such a reservoir.

For fish, a low parallelepiped with a base height of up to 70 cm is preferable. The height of the reservoir for fish is not a fundamental factor, but the plants will receive the necessary light.
