Does ading a longer barrel to a gun increase velocity of the fired projectiles?

Yes, but there is a point where the round reaches the max velocity it can achieve, and any extra barrel length past that point is a bit useless.

What is the lowest velocity?
Lowest velocity round such as a 30.06 barrel has a longer barrel life.
When a rifle with a longer barrel is fired the force of expanding gases acts on the bullet for a longer distance what effect does this have on the velocity?
To a point, the velocity of the bullet will increase. However, at some point, the gasses driving the bullet have maxed out, and beyond that point, the bullet will begin to slow from friction with the barrel. For a .22 LR cartridge, that length is about 12 inches. Larger cartridges have a greater "Max velocity" length, but there is a point of no more gain, and the start of loss of velocity.
Can adding a longer barrel to a gun improve it any?
Usually, yes. A longer gun barrel allows the bullet to accelerate longer and thus increases its velocity. But it is a complicated problem. A short barrel and a large powder load has about the same velocity as a smaller load and a longer barrel. A longer barrel suffers more wear. Really big naval guns were good for a limited number of shots and each shot was numbered, being bigger for every shot.
If a cannonball is shot from a longer barrel cannon rather than a shorter barrel cannon it willl have a?
Longer (effective) range. Longer barrels on a firearm allow for more complete burning of the propellant, which results in a higher muzzle velocity, which in turn results in a longer effective range, when compared to an identical weapon with a shorter barrel.
A cannonball shot from a cannon with a long barrel will have a greater muzzle velocity because the cannonball receives a greater what?
Gunpowder burns, heat and pressure rise, ball accelerates Guns are designed so that the potential of the gunpowder is translated into momentum of the cannonball, if you hold the barrel diameter and cannonball size the same, the only way to increase the momentum (and velocity) is to apply the gunpowder force (pressure) for longer, this means: 1) A longer barrel 2) More gunpowder
What is the velocity of 303 rifle bullet?
2441 feet per second when fired from the British SMLE rifle. Velocity will vary when fired from rifles with a longer or shorter barrel.
How does the length of a shotguns barrel effect muzzle velocity?
With modern powders not very much. In the past, the longer barrel gave the powder a chance to burn more thoroughly.
How does the term 45 Caliber apply to the 16 inch projectiles of the main battery naval rifles of the Missouri class Battleships The projectiles are close to 5 feet long?
Caliber (for artillery) is the ratio of the barrel length to the bore diameter. So a 50 caliber 16" gun (Iowa-class) is longer than a 45 caliber gun (North Carolina-class), which gives a higher muzzle velocity, and therefore greater range and penetration.
Does the velocity of a 22 caliber bullet change with the length of the barrel?
Yes. The velocity of all common cartridges changes with the length of the barrel. In the case of a .22 LR, they develop the maximum velocity between 12 and 16 inches of barrel. Shorter than that, the gasses from the gunpowder have not accelerated the bullet as much as they can. Longer than that, gasses reached their max acceleration, and the bullet is now slowing from friction in the barrel.
Why is the speed of a cannonball greater when shot from a cannon with a longer barrel?
The energy needed to move a cannonball is created by burning fuel--usually gunpowder but nothing says they couldn't make a cannon that burned propane to fire projectiles. Anyway, if you're firing a round the speed of that cannonball is determined in part by how long the energy's being applied to it. The longer the barrel is, the longer the energy will be applied and the faster the cannonball will go.
Why does a rifle have a long barrel?
The longer the barrel allows several things:Higher velocity bullets ( From better containing of burning propellant )The longer barrel help the bullet become and stay stable thus creating a more accurate firearmThe higher mass of the long weapon helps control and direct the recoilThe longer weapon allows more stable and accurate aimingThe longer barrel allows the use of flash suppression and gas redirection with out risking the operators health
Does a longer airsoft barrel account to anything?
Longer barrels to increase accuracy and fps slightly, but getting tighter bore barrels has a much greater effect on both. Also, the effect of barrel length works in a way that the longer a barrel is, the less effect a barrel extension has. For example, replacing a pistol barrel with one that is 3 inches longer has a much larger effect on the pistols accuracy than adding 3 inches to a sniper rifle barrel has on the sniper's accuracy. Fps increases with increased barrel lengths are usually negligible, while tight bore barrels can increase fps by up to 15%. If you are going to change the barrel I would recommend a tight bore over a longer barrel (if you can do both then go right ahead). When buying a stock gun, barrel length is something to consider though, because the differences can be quite significant, especially between "normal" rifles and bullpups.
