Tanks and tanks are used to transport and storing various types of fuel, oil, water and gas, some building materials, chemicals, and food products. Many do not know how to calculate the capacity of the tank, because they may have a different geometric shape:
- Cone;
- Cylinder;
- Spheres;
- Rectangular parallelepiped.
In our article, you will get acquainted with the nuances of the calculation for specific geometric bodies.
How to find out the volume of rectangular packaging
In the field of construction, all indicators of volume are shown to specific values. Calculations can be carried out in liters or DM 3 But most often cubic meters are used to determine the number of one material. How to calculate the cubature of the simplest rectangular capacities we describe further on a specific example.
To work, we will need a container, a construction roulette and a notebook with a handle or pencil for computation. From the course of geometry it is known that the volume of such bodies is calculated by multiplying the length, widths and heights of the product. The calculation formula comes down to the following
V \u003d A * B * C, where a, b and s - side of the container.
For example, the length of our product is 150 centimeters, the width is 80 centimeters, the height of 50 centimeters. For the correct calculation of the cubature, the specified values \u200b\u200bare translated into meters and carry out the necessary calculations V \u003d 1.5 * 0.8 * 0.5 \u003d 0.6 m3.
How to determine the volume of spherical
Spherical products are found in our life almost every day. It can be a bearing element, a soccer ball or a type of ballpoint pen. In some cases, we need to learn how to calculate the cube of the sphere to determine the amount of fluid in it.
According to experts, the formula is used to calculate the volume of this figure V \u003d 4 / 3ԉr3Where:
- V - calculated the volume of the part;
- R- radius of the sphere;
- ԉ - a constant value that is equal to 3.14.
To carry out the necessary calculations, we need to take the roulette, fix the beginning of the measuring scale and measure the measurement, and the roulette tape should pass along the equator of the ball. After that, the diameter of the part will recognize, dividing the size by the number ԉ.
And now you will get acquainted with a specific example of calculating for the sphere, if its circumference is 2.5 meters. First, we define the diameter of 2.5 / 3.14 \u003d 0.8 meters. Now we substitute this value in the formula:
V \u003d (4 * 3,14 * 0.8³) / 3 \u003d 2,14m³
How to calculate the volume of the tank made in the form of a cylinder
Such geometric shapes are used for storing food, fuel transportation and other purposes. Many do not know how to calculate the volume of water, but the main nuances of this process we describe further in our article.
The height of the liquid in the cylindrical container is determined by the special device of the metr stitch. In this case, the tank capacity is calculated by special tables. Products with special measurement tables of volume in life are rare, so we will come up to solving the problem by another way and we describe how to calculate the volume of the cylinder according to the special formula - V \u003d S * L, where
- V- The volume of the geometric body;
- S is the area of \u200b\u200bthe product cross section in specific units of measurement (m³);
- L is the length of the tank.
The indicator L can be measured with the help of the same roulette, but the area of \u200b\u200bthe cylinder cross section will have to be considered. The indicator S is calculated by the formula S \u003d 3.14 * D * D / 4, where D is the diameter of the cylinder circle.
And now you will get acquainted with a specific example. Suppose the length of our tank is 5 meters, its diameter is 2.8 meters. First, we calculate the cross-sectional area of \u200b\u200bthe geometric figure S \u003d 3.14 * 2.8 * 2.8 / 4 \u003d 6.15m. And now you can proceed to the calculation of the volume of the tank 6.15 * 5 \u003d 30.75 m³.
With the help of an online calculator, you can correctly calculate the volume of the type of capacity: cylinder, barrels, tanks, or liquid volume in any other horizontal cylindrical container.
We define the amount of liquid in an incomplete cylindrical tank
All parameters indicate millimeters
L. - Height of the barrel.
H. - Liquid level.
D. - Tank diameter.
Our program in online mode will calculate the amount of fluid in the container, will determine the surface area, free and common cub.
The determination of the main parameters of the cubature of the tanks (for example, the usual barrel or tank) should be based on the geometric method of calculating the capacity of cylinders. In contrast to the methods of calibration of the container, where the calculation of the volume is performed in the form of real measurements of the amount of fluid by the measuring line (according to the testimony of the metrshtok).
V \u003d S * L - the formula for calculating the volume of the tank of the cylindrical form, where:
L - body length.
S is the cross-sectional area of \u200b\u200bthe tank.
According to the results obtained, the calibration tables of the containers are created, which are still called targeting, allow you to determine the weight of the liquid in the tank in the proportion and volume. These parameters will depend on the filling level of the tank, which can be measured using the metr stitch.
Our online calculator provides the ability to calculate the capacity of horizontal and vertical containers on the geometric formula. You can find out the useful capacity of the tank more accurately if you correctly determine all the main parameters that are listed above and participate in the calculation.
How to determine the basic data
Determine the lengthL.
With the help of a conventional roulette, you can measure the length L of a cylindrical tank with a non-planning bottom. To do this, you need to measure the distance between the crossing lines of the bottom with the cylindrical body of the container. In the case where the horizontal tank with a flat bottom, then in order to determine the size L, it suffices to measure the length of the tank over the outside (from one edge of the tank to the other), and from the resulting result, the bottom thickness obtained.
Determine Diameter D.
The easiest way to determine the diameter D of the cylindrical barrels. For this, it is enough with the help of a roulette to measure the distance between two any extreme dots of the lid or edge.
If it is difficult to correctly perform the calculation of the diameter of the container, then in this case you can use the measurement of the circumference length. To do this, with the help of ordinary roulette, we wrap the entire tank around the circumference. For correctly calculating the circle make two measurements in each section of the tank. For this surface, the measured must be clean. Having learned the average circumference of our capacity - the Locre, we turn to the definition of the diameter according to the following formula:
This method is the easiest, as it is often measured by the diameter of the tank, is accompanied by a number of difficulties associated with the climb on the surface of various types of equipment.
Important! Diameter measurements are correct to fully perform in three different sections of the container, and then perform the counting of the average value. Since often, these data may differ significantly.
The averaged values \u200b\u200bafter three measurements allow you to minimize the error of calculating the volume of the cylindrical reservoir. As a rule, the storage tanks used during operation are exposed to deformation, may lose strength, decrease in size, which leads to a decrease in the amount of fluid inside.
Determine the levelH.
To determine the level of fluid, in our case it is H, we need a meterstock. With this measuring element, which is lowered to the bottom of the tank, we will be able to accurately determine the parameter H. But these calculations will be correct for reservoirs with a flat bottom.
As a result of the counting of online calculator, we get:
- Free volume in liters;
- The amount of fluid in liters;
- Liquid volume in liters;
- The total area of \u200b\u200bthe tank in m²;
- DNA area in m²;
- Side surface area in m².
Of course, drivers most often do not allow a gasoline light bulb in the car, which warns about low fuel in the tank. This warning indicates that it is time to avoid the car. But should we immediately go to refueling and refueling the car? How much time do we have time before gasoline or diesel fuel end in the car? Here is a detailed table in many models of cars, which discloses in detail information about how much fuel remains in the tank, after a low-level gasoline or diesel fuel has appeared on the dashboard.
The table published below is an exemplary value for a particular car model. Please note that the data is given for cars produced until 2015 inclusive. Also keep in mind that some values \u200b\u200bin the table may differ slightly from real indicators.
But on average the following values \u200b\u200bare obtained: passenger cars, after the fuel level light lights up in the tank, can still drive about 50 kilometers, when both SUVs and crossovers, which are usually increased fuel tanks, can drive on a burning fuel light bulb Approximately 150 kilometers.
Does this mean that car owners can, when alerts appear on a low fuel dashboard, do not rush to refueling? Of course not. Especially if you are in an unfamiliar area and do not have an idea of \u200b\u200bwhat distance will be as follows.
That is, despite the fact that in any car, the fuel tank has a certain fuel reserve, after the burning lamp appears, signaling about a low level of fuel in the tank, you should fix your car as soon as possible and not allow this warning to appear again. Always keep the fuel level in the tank until the burning fuel light on the dashboard appears.
Is it dangerous to ride with low fuel in the tank?
Many people do not know, but besides the risk, stay without fuel, in case of ignoring a low-level fuel prevention, there are still a number of problems with which any car owner can face, which often travels on an empty tank.
For example, frequent trips on an empty tank can prematurely output the catalyst in the exhaust system, which will have to be repaired or purchased a new one, which is associated with huge cash spending.
Including frequent rides at a low level of fuel in the tank can be due to the gas station. The fact is that the fuel that we refuel on the gas station is not really clean (especially in Russia) and it contains various factions of pollution that settle at the bottom of the tank. With a low level of fuel, we risk that such a precipitate can get into the fuel pump through the gas station. Especially ,. It is at this moment that the particles of the tank can fall into the fuel pump. At a normal level of fuel, a similar risk of pollution of the fuel system is minimal.
So if you do not want to spoil your own, then regularly and fill your car on time, without bringing the fuel level to low values \u200b\u200bthat lead to the appearance of a burning lamp on the dashboard.
Is the reserve of the course on the onboard computer of the car?
Many car owners are often focused on the testimony of a vehicle on-board computer, which shows you a possible reserve of the stroke. Therefore, some drivers and bring the car to a low level of fuel, relying on an indicator of the on-board computer, believing that the specified reserve of the truthful stroke.
Also, many drivers when a low-level fuel warning appears, immediately look at the side of the on-board computer in order to find out how much another car can drive on the fuel, which remains in the tank (stroke).
But, unfortunately, the stroke is not accurate, as it is based only on the average values \u200b\u200bof your movement along the road in the past.
The fact is that the electronics of the car will not be able to show the truthful reserve of the course, as can not consider your current conditions of movement in real time, affecting the consumption of gasoline or diesel fuel.
For example, if you appear on the dashboard lamp, warning you about a low fuel level in the car's tank, drove along the highway, and now they got into a plug, the reserve of the course displayed on the on-board computer is actually incorrect since this indicator is calculated when The movement along the highway, where fuel consumption is actually much less than in dense traffic in the city.
Therefore, do not expect that when you prevent a low fuel level, you can travel still a lot.
So how much fuel in the tank remains from the moment of the appearance on the dashboard of the burning light bulb and how many kilometers can still be driving until the fuel is complete?
If you can still answer the first question, you can still be enough, then what the distance you can drive on an empty tank, after the fuel lamp caught fire on the dashboard, to say unequivocally very hard because it depends on the actual fuel consumption of your car at a certain point time.
And the flow depends on many factors, ranging from your driving style and weather conditions, as well as ending with rubber and road surface installed on the car.
We already, which disclosed in detail information about the stream of the course on the empty tank. .
The same article complements the last, and also expands the useful information for motorists.
Here is a detailed table on car models, which shows detail how much fuel in the tank remains in your machine after a burning light will appear on the dashboard, a low fuel warning driver. Also from the table you will learn how the distance on average you can drive after a warning about an empty tank.

Yes, sometimes we can be in a situation where it will not work on time to get used your car. In this case, on the tidy, in any case, a warning will appear sooner or later that gasoline or diesel ends soon.
We advise you not to ignore this warning of the electronics of the car. But there is no need to panic. You still have time to find gas station to fix your car. Thanks to this table, you can approximate how much fuels you have in the tank, as well as what is the stock of the car, after the lamp appears on the low fuel level in the tank.
The volume of filling gasoline can be less if liquid accumulates in the tank. Capacity options cannot be changed, but the composition of its contents will be different. If you get into the water tank, you can observe the following:
- difficulties with the vehicle in the morning;
- uneven engine operation;
- the need for longer to warm the car before launching.
Water enters the tank for various reasons. You can remove it in one way:
- Mix with pure alcohol gasoline (from 200 to 500 milliliters), after which to pour these liquids into the tank under fuel.
- Through a spool on the fuel ramp. This is a more complex way, as you need to merge with a hose liquid into any transparent container. To do this, supply voltage to fuel pump with a diagnostic pad.
- Digging manually with a long and thin hose from the dropper. You will need to install a bucket or any container under the liquid into the observation pit or just below the tank level.
You can prevent water from entering the benzobak with the help of maintaining a constant fuel level in it (it is desirable to refuel "under the string"). If you need to add gasoline into a rainy or foggy day, fill the tank for fuel by 100%. This simple technique will allow you to displace the humid air from the system, which settles the condensate while driving. Later in the fall, pour into the system of clean alcohol (enough 200 milliliters) to remove the accumulated water and prevent its freezing.
We decided to spend this experiment due to periodic complaints of car owners at gas stations, which allegedly do not fuel fuel to the tank and write in social networks, which fastened more than the volume of the tank at the dressing station.
The rationale for this is the fill to the almost empty tank of the larger fuel, which is indicated in the car operating manual.
We deepened in the construction of cars and found technological prerequisites explaining different real and documentary (in TTX cars) the volume of the fuel tank. Now we decided to confirm our arguments and went with five different cars on the AZK of one of the major fuel market operators.
Two cars with diesel engines participated in the test - Citroen Grand C4 Picasso and Renault Duster and three gasoline cars - Volkswagen Bora, Skoda Octavia A5 and Ford Mondeo. All five cars came to the place of experiment on the minimum fuel residue in the tank.
Preparation for test
Before starting the refueling, we asked for AZK employees to check the accuracy of the filling column. To do this, at all refills there are a special 20-liter dimensional container with high-precision calf, which makes it possible to determine the belling or overflow with an accuracy of 20 ml.
After wetting the dimensional capacity (mandatory procedure), 20 liters of fuel were poured into it. The little worker confirmed that the column pours exactly, after which we began to fill our cars.
Result refueling
The main condition for refueling the aforementioned cars was filling fuel to the tank for the sickness of the throat, i.e. We have already seen that fuel - under the top of the neck. Looking in advance, we note that in fact there are more fuels in the tanks of all 5 cars, rather than in TTX (in one case - by as much as 17 l!).
First refrain Citroit Grand C4 Picasso. With a 55-liter tank (in TTX) and the residual one division of the electronic fuel level sensor in the tank was flooded with 51 liters of diesel fuel. Excess - 2-4 l.
Renault Duster. In its almost empty tank, 62 liters of fuel at the factory data is only 50 liters. Excess - 15-17 * l.
In a car VW Bora. Filled a little more than 52 liters of gasoline under 55 liter factory data. Taking into account the residue, the TTX can reach at 3-5 * l.
Real volume of tank Skoda Octavia A5. Significantly exceeded the data claimed in TTX. It was poured into it 62 liters at a rate of 55 liters. Excess - 12-14 * l
In a 70-liter tank Ford Mondeo. With a residual mileage, almost 71 liters of gasoline placed 26 km. Those. Real excess volume is 8-9 * l.
The results of this test confirmed our theoretical conclusions: the real volume of the fuel tank differs from the specified automaker for significant limits ( from one to 10 or more liters).
So the drivers should keep in mind: if you flooded a few liters at the dressing, which you expected, this is not a reason for the scandal. This is most likely the feature of your fuel tank.
* Taking into account unaccounted 4-5 liters of fuel below the floating gas tank
