A gun barrel is a crucial part of gun-type ranged weapons such as small firearms, artillery pieces and air guns. It is the straight shooting tube, usually made of rigid high-strength metal, through which a contained rapid expansion of high-pressure gas(es) is introduced (via propellant combustion or mechanical compression) behind a projectile.

These finishing barrels frequently aged a different spirit such as rum or wine. English And they claim they have billion barrels of oil , which I do not believe.

Handy transport and storage barrel. Can also be used as a fermenter (with adding a water lock on the lid). Large opening with hermetically closing the-bath-studio.infot weight: 7,50 Kg.

Das Volumen der US und brit. Flüssig-Unze ist nicht identisch. Das Volumen eines Objekts kann anhand der vom Objekt verursachten Flüssigkeitsverdrängung gemessen werden. Wenn beispielsweise ein Messbecher 1 Liter Wasser enthält und der Wasserspiegel auf 1,5 Liter steigt, sobald das Objekt in den Becher gegeben wird und es komplett mit Wasser bedeckt ist, beträgt das Volumen des Objekts 0,5 Liter.

Diese Methode funktioniert nur mit Material, das kein Wasser absorbiert. Produkt der Länge, Breite und Höhe. Wenn die Höhe nicht bekannt ist, kann sie anhand der dritten Seite und dem Winkel zwischen dieser Seite und der Grundlinie berechnet werden. Wenn wir sie jeweils a und und die Länge l sowie die Breite w nennen, können wir die folgende Formel zur Berechnung des Volumens V verwenden:.

Andere Arten zur Berechnung des Volumens können von den Eigenschaften eines rechtwinkligen Dreiecks abgeleitet werden. Anhand von Algebra kann man das Verhältnis der Volumen von Zylinder: Kegel ableiten, das 3: Dieser Artikel wurde von Kateryna Yuri verfasst.

Technisches Englisch mithilfe unserer Videos lernen! A gun barrel is a crucial part of gun -type ranged weapons such as small firearms , artillery pieces and air guns. It is the straight shooting tube, usually made of rigid high-strength metal , through which a contained rapid expansion of high-pressure gas es is introduced via propellant combustion or mechanical compression behind a projectile in order to propel it out of the front end muzzle at a high velocity.

The hollow interior of the barrel is called the bore. The measurement of the diameter of the bore is called the caliber. Caliber is usually measured in inches or millimetres. The first firearms were made at a time when metallurgy was not advanced enough to cast tubes capable of withstanding the explosive forces of early cannons , so the pipe often built from staves of metal needed to be braced periodically along its length for reinforcement, producing an appearance somewhat reminiscent of storage barrels being stacked together, hence the English name.

Gun barrels are usually metal. However, the early Chinese, the inventors of gunpowder, used bamboo , which has a strong, naturally tubular stalk and is cheaper to obtain and process, as the first barrels in gunpowder projectile weapons such as the fire lances. Early European guns were made of wrought iron , usually with several strengthening bands of the metal wrapped around circular wrought iron rings and then welded into a hollow cylinder.

Early firearms were muzzle-loading , with the gunpowder and then the shot loaded from the front end muzzle of the barrel, and were capable of only a low rate of fire due to the cumbersome loading process. The later-invented breech-loading designs provided a higher rate of fire, but early breechloaders lacked an effective way of sealing the escaping gases that leaked from the back end breech of the barrel, reducing the available muzzle velocity. Early cannon barrels were very thick for their caliber.

This was because manufacturing defects such as air bubbles trapped in the metal were common back in the days, and played key factors in many gun explosions; these defects made the barrel too weak to withstand the pressures of firing, causing it to fail and fragment explosively.

A gun barrel must be able to hold in the expanding gas produced by the propellants to ensure that optimum muzzle velocity is attained by the projectile as it is being pushed out. If the barrel material cannot cope with the pressure within the bore, the barrel itself might suffer catastrophic failure and explode, which will not only destroy the gun but also present a life-threatening danger to people nearby.

Modern small arms barrels are made of carbon steel or stainless steel materials known and tested to withstand the pressures involved. Artillery pieces are made by various techniques providing reliably sufficient strength. In firearms terminology, fluting refers to the removal of material from a cylindrical surface, usually creating rounded grooves, for the purpose of reducing weight. This is most often done to the exterior surface of a rifle barrel, though it may also be applied to the cylinder of a revolver or the bolt of a bolt-action rifle.

Most flutings on rifle barrels and revolver cylinders are straight, though helical flutings can be seen on rifle bolts and occasionally also rifle barrels. While the main purpose of fluting is just to reduce weight and improve portability, when adequately done it can retain the structural strength and rigidity and increase the overall specific strength.

Fluting will also increase the surface-to-volume ratio and make the barrel more efficient to cool after firing, though the reduced material mass also means the barrel will heat up easily during firing.

The chamber is the cavity at the back end of a breech-loading gun 's barrel where the cartridge is inserted in position ready to be fired. In most firearms rifles , shotguns , machine guns and pistols , the chamber is an integral part of the barrel, often made by simply reaming the rear bore of a barrel blank, with a single chamber within a single barrel.

English barrels of oil are produced each day but the benefits of those barrels of oil never reach the people of Sudan. English So here you are, that the cost of all this to the world is 89 million barrels of oil , give or take a few barrels, every day. English We use over five billion tons of coal, 30 billion-plus barrels of oil -- that's a hundred million barrels a day.

Das sind hundert Millionen Fässer am Tag. English How does that translate to barrels of oil equivalent? English The International Energy Agency called on its member states to release 2 million barrels of oil a day over 30 days. English Since barrels of oil are paid for in dollars, the increase has a greater impact upon countries whose currencies have lost ground against the dollar. English Although they coexist with powerful international interests, in a territory that produces hundreds of millions of barrels of oil , they endure the most extreme poverty.
