víztávre

Víz távre is a Hungarian term that translates to "water distance" or "water span." It generally refers to the horizontal distance that a projectile, such as a bullet or arrow, travels through water before losing its effective velocity or becoming significantly impeded. This concept is important in various fields, including ballistics, diving, and aquatic ballistics.

The víz távre of an object is influenced by several factors. The object's shape and density play a significant role, as does its initial velocity. Denser and more streamlined objects will typically penetrate water further than less dense or more irregularly shaped ones. The properties of the water itself, such as its viscosity and the presence of currents, also affect the víz távre. For instance, saltwater generally offers more resistance than freshwater.

In ballistics, understanding víz távre is crucial for determining the effective range of firearms underwater, particularly for military or specialized applications. For divers, it can inform how far they might expect a thrown object to travel or how to anticipate the trajectory of a falling object. The concept highlights the dramatic change in resistance and speed experienced by projectiles when transitioning from air to water.
