How many liters of methane are in a cube?

As people call it the “long-suffering” cubic meter – m3. Abbreviations such as cube and cubic meter are especially often used, universally accepted and understood by everyone. Our “people” do not change liters, their mentality does not allow it. The question of how many liters are in 1 cubic meter or one cube of methane may be of purely educational interest. Previously, this worried mainly schoolchildren and junior students solving problems in physics. However, today, people who are far from the school curriculum are beginning to remember long-forgotten information. Perhaps they want to check the accuracy of the calculations made on their own when converting liters to cubes, cubic meters or cubic meters - m3. Many drivers are accustomed to correlating fuel consumption and the mileage that a car can travel after refueling, based on the number of liters of gas filled into the cylinder. At gas stations, methane is counted in cubes. The task is quite simple, but often “complicated” by incorrect formulations of the question. Therefore, let's take a closer look.

Along the way, I consider it necessary to clarify the term: liquefied gas, which is often associated with the question: how many liters of methane are in a cube. Liquefied gas itself is not a separate “type” of methane, but a unique state of aggregation into which any existing gas can be “transformed.” Technically, to obtain a liquefied state, a gas or air (which is also a gas) is cooled to a temperature at which it becomes a liquid. This technology is widespread and has practical meaning not for methane, but for propane and butane. The cooling temperature with gas liquefaction technology in this case is minus 160 degrees Celsius. That is why propane, butane and proportional mixtures of these gases are most often counted in liters. Methane is usually not liquefied, but compressed. This is another gas storage technology in which it does not turn into a liquid state, remaining in a “normal” state of aggregation. Therefore, methane at gas stations is counted in cubic meters.

Cubic meters and liters are units of volume that do not themselves take into account any additional physical characteristics of methane or its chemical composition. Pure mathematics. Therefore, let's take a look at the reference book of weights and measures. To do this, it is most convenient to use the ratio from the table of volumes, which clearly indicates that one cubic meter of any substance contains 1000 liters of the same substance. At the same time, it does not matter at all what kind of gas we are measuring. Hot, cold, warm, discharged, compressed, liquefied, frozen or whatever. Moreover, volumetric measurement is also possible not only for liquids and gases, but for bulk materials and theoretically for solids. For example, if we measure sand rather than gas in liters (let’s say we need this for some reason), then one cube of sand will contain the same 1000 liters.

You can often find very strange explanations for the question of how many liters of methane are in a cube, boiling down to the fact that temperature, pressure, density or other physical parameters supposedly influence this ratio. This is actually a myth. The number of liters of “hot” methane in one cubic meter m3 and the number of liters of liquefied methane will be the same - 1000 liters. As, indeed, the number of liters of compressed methane or frozen to the state of ice: in one cube, also 1000 liters.

The chemical composition of methane, its purity or the presence of any impurities, do not in any way affect the number of liters in a cube of methane.

Another thing is that gas can be in the state of both a liquid and a solid (ice). Significantly changing its volume depending on temperature, especially during the transition from one state of aggregation to another. This is due to a change in its density, and therefore weight. That is, a liter or 1 cubic meter of the same methane can have different masses. But, that's a completely different story. It is completely incorrect, for example: to take liters of methane in ice state and compare it with the amount of heated methane in 1 cubic meter. This is absurd when the question is posed this way. At constant temperature and pressure, the amount of methane measured in liters will be the same in 1 cubic meter, those same 1000 liters. The presence of impurities in the gas refers to its chemical composition, and can actually affect the mass of one cubic meter of methane or one liter. But the ratio of how many liters are in a cube will remain unchanged. For clarity, you can imagine exactly the same “story” with the same sand. Black sand, white, fine, coarse, quartz or with an admixture of clay - it doesn’t matter at all. In any case, exactly 1000 liters of substance will “fit” in one cubic meter. No more and no less, subject to the immutability and constant of its physical characteristics.

Physical meaning of translation

In a physical sense, everything is quite simple. The translation is carried out in the same way for any gases, liquids or bulk materials as follows:

• 1 cubic meter contains 1000 liters,
• 1 liter equals 0.001 cubic meters
• the table shows the quantity contained in 1 cube (1 cube = 1000 cubic decimeters, etc.).

For example, 15 cubic meters of natural gas used by the meter equals 15,000 liters. When converting these values, the temperature of the fuel, the amount of impurities and other factors do not matter.

a) Consumption coefficient of propane-butane (l) compared to gasoline (l) = 1.15; those. if gasoline consumption is 15 l/100 km, then propane consumption will be 17.25 l/100 km.

b) Methane consumption coefficient compared to gasoline = 0.9; those. with a gasoline consumption of 15 l/100 km, methane consumption will be 13.5 m3/100 km.

c) The volume of methane is measured not in liters, but in cubic meters. A 100 liter cylinder holds 25 m 3 of methane (100 l / 4 = 25 m 3).

How many kilograms are there in a liter of methane?

Mass is a characteristic of a body, which is a measure of gravitational interaction with other bodies.
Volume is a quantitative characteristic of the space occupied by a body, structure or substance.

Density is a physical quantity defined as the ratio of body mass to body volume.

The relationship between liters and kilograms of methane is determined by a simple mathematical formula:

V – volume; m – mass; p – density.

In the calculation, the density of methane = 0.7168 kg/m3 was taken.

The density of methane can vary depending on temperature and pressure. You can find the exact density of methane in reference books.

The number of liters contained in a cubic meter of gas is not as simple a question as it might seem at first glance, given the peculiarities of using gas fuel. Let's consider ways to convert the volume of gases used as fuel, taking into account their characteristics.

How many liters are in 1 cubic liter?

Let's start with a lyrical digression, namely from a school physics course. It is known that the generally accepted unit of volume measurement is the cubic meter. 1 cubic meter is the volume of a cube whose side is exactly one meter.

1 cubic meter

This unit is not always convenient and it is for this reason that others are very often used - liters - also known as cubic decimeters and cubic centimeters.

As practice has shown, the most convenient unit of volume measurement is the liter, which is the volume of a cube whose length is 1 dm or 10 cm. Thus, we find that all the questions of how to convert a dm cube into cubes are equivalent to the question: how to convert liters into cubes, because 1 dm. cube = 1 liter.

Calculation example

It is necessary to determine how many cubic meters of gas one cylinder with a 50-liter propane-butane mixture contains if you pass its contents through a gas meter:

• the mass of the gas mixture pumped into it is about 21 kilograms;
• volume in m³ is equal to 50/5 = 10;
• after adjusting for the filling of the cylinder, we get 10 × 0.85 = 8.5 m³.

This indicator may vary depending on the ambient temperature, since when it decreases, the pressure inside the container decreases, with a corresponding decrease in the volume of fuel.

But the use of liters of gas in cubic meters is only relevant as an approximate calculation. When purchasing this type of fuel, kilograms of the gas mixture and the pressure inside the container are important, and when using individual metering devices, a standard unit of measurement is used - cubic meters, the conversion procedure of which does not depend on the composition of the gas and is determined by a simple arithmetic calculation in the ratio of 1 to 1000.

At gas stations, methane is counted in cubes. The task is quite simple, but often “complicated” by incorrect formulations of the question. Therefore, let's take a closer look.

Types of methane cylinders

Depending on the materials of manufacture, automobile containers for compressed natural gas (CNG) are divided into types:

Type 1 (KPG-1) - all-metal vessels made of alloy or carbon steel, with a wall thickness of 5.5-9.5 mm (thickness depends on the volume of the tank). They have a seamless design and are made primarily from steel pipes using the hot rolling method. After molding the bottom and neck, the cylinder goes through a number of stages:

• heat treatment (normalization) to impart strength properties
• cooling
• machining with drilling a hole for the valve
• taper thread cutting
• cleaning, descaling
• tests (hydraulic, pneumatic, ultrasonic)
• marking
• coloring

Lightweight CNG-1 cylinders are also produced by deep drawing from sheet steel (without welds). Such containers have all the necessary strength parameters, but at the same time their weight is reduced to 20% in relation to pipe vessels.

Cylinders of the first type are considered very reliable, relatively inexpensive, but they are the heaviest.

Type 2 (KPG-2) – metal-plastic cylinders. Made from thinner steel (4.8-6 mm). Strength is achieved through external reinforcement. Strengthening occurs by the method of continuous winding of a polymer material (aramid, glass, carbon fibers) onto the cylindrical part of the liner (body).

Metal composite tanks CNG-2 are quite reliable and have a relatively low weight. Their disadvantage is their relatively high price.

Type 3 (KPG-3) – containers with a metal liner made of light aluminum alloys with an external continuous winding of polymer materials. CNG-3 cylinders are among the lightest and most expensive.

Type 4 (CNG-4) - composite methane cylinders have a non-metal (plastic) liner with a polymer shell over the entire surface. A metal insert is used for the neck. CNG-4 containers are ultra-light, but very expensive.

Use of liquefied gas

It’s a little more complicated with liquefied gas. It is widely used:

• in modern industrial production;
• in thermal and electric power engineering;
• as a reserve stock during the period of the most intensive consumption by the population;
• as a replacement for traditional gasoline or diesel fuel for road transport;
• for domestic purposes.

In the household, it is advantageous to use liquefied gas in cylinders for the operation of gas-consuming household appliances, provided there is no centralized supply line.

Various mixtures of propane and butane are used for liquefaction. The use of methane is not economically profitable, since at room temperature the pressure in the system increases so much that to ensure safety it is necessary to create containers with large wall thicknesses and use materials of increased strength.

The change in gas volume during the transition from the liquid phase to the gaseous phase is determined by the following factors:

• chemical composition;
• pressure;
• temperature;
• density and specific gravity.

To calculate the number of liters of liquefied gas per cubic meters of fuel that have turned into a gaseous state, it is necessary to use the specified characteristics. But since it is difficult to reliably establish the exact composition of the mixture in the cylinder, it is necessary to be guided by an approximate ratio, according to which at a standard temperature of 20 degrees, 1 liter of liquefied gas will produce 200 - ordinary gas. Therefore the formula applies:

Okub = Ol/5

• Cube – volume in cubic meters;
• Ol – volume in liters.

When making calculations, it is necessary to additionally take into account that, for safety reasons, gas cylinders are filled to no more than 85 percent of the total volume.
