How many liters of gas in a 50-liter tank? How many cubes of gas in a 50-liter tank?

When a gas enters a rural settlement, civilization comes into it. Stove heating, or individual water heating with a solid fuel boiler, is not only a romantic crackle of firewood in the furnace. Heating with solid fuel is always soot, smoke and soot, the need for annual repainting of ceilings. And in addition to the troubles associated with permanent mud, it is necessary to procure or purchase and somewhere to store a stock of firewood for the whole winter.

Unfortunately, not all natural gas pipeline has been conducted. In many settlements, residents have to be content with gas in cylinders. And people are interested, but how many liters of gas are in the 50-liter bottle?

What is household gas

Let us recall the fundamentals of school organic chemistry. The first limiting hydrocarbon is methane. The molecule of this gas consists of one carbon atom, surrounded by four hydrogen atoms.

If you slightly lengthen the chain - instead of one of the hydrogen atoms "attach" one carbon, for the remaining three of its bonds add hydrogen atoms, - will get the next member of the family of saturated hydrocarbons, ethane.

Starting from the beginning of the chain, we have:

• Methane CH ₄ ;
• Ethane C ₂ H ₆ ;
• Propane C ₃ H ₈ ;
• Butane C ₄ H ₁₀ .

The last two compounds - propane and butane - are the contents of domestic gas cylinders.

The physical properties of these chemicals

Propane at normal atmospheric pressure is a liquid in the temperature range from -187.7 to -42.1 ° C. Below this interval, propane crystallizes, and above, respectively, passes into a gaseous state. Butane has this range: -138.3 ... -0.5 ° C. As we can see, the transition temperatures in the liquid for both gases are not much lower than zero, so that they can be easily liquefied by increasing the pressure.

Methods of gas storage

In everyday life, as a rule, a mixture of propane-butane is used. In private houses for storing the liquefied mixture, standard 50-liter gas cylinders are used. A little differently comes with gas supply of high-rise buildings. Well, how many liters of gas in a 50-liter bottle can fit?

And to change the cylinders with 42 liters of gas (this is how much liquefied gas is stored in the cylinder), plus the weight of the cylinder itself on all floors and apartments ... Therefore, in such cases, in the yard of the house, a generally grounded storage is arranged, to which a gas mixture is delivered by special gas carriers. In a special device, it is transferred to the gaseous phase and in this form enters the domestic pipeline.

The volume of the gas cylinder

So how many cubes of gas in a 50-liter tank? To answer this question, it is necessary to determine which gas we are interested in. A liquid mixture of gases in the cylinder is filled with 42 liters. But how much is in kilograms, cubic meters? The density of liquefied: propane - 0.528 kg / l, butane - 601 kg / l.

In order to find out how many liters of gas in the 50-liter bottle, we will make small calculations.

Thus, how many liters of gas in a 50-liter tank depends on the composition of the tank. Assuming that the cylinder is filled with one propane - 22.44 m ³ , butane - 16.67 m ³ . But since in a household a mixture of these chemical compounds is used, the indicator will be somewhere in the middle.

If we assume that propane and butane are in the cylinder in equal parts, then the answer to the question of how much gas in the 50-liter bottle (m3) is about 20.

Safety measures when handling gas cylinders

• Never remove labels or labels from cylinders.
• Do not lift or move the cylinder by holding the valve.
• Leaks should be determined with a soap solution, not a lit match.
• Open the cylinder valve gently.
• Never heat the cylinder.
• Independent pumping (overflow) of liquefied gas into other containers is prohibited.
