térfogatkiszorító

A térfogatkiszorító, in English known as a displacement volume or displacement effect, refers to the volume occupied by a submerged object within a fluid. This concept is fundamental in understanding buoyancy and Archimedes' principle. When an object is placed in a liquid, it pushes aside, or displaces, an amount of liquid equal to its own volume. This displaced liquid exerts an upward buoyant force on the object.

The magnitude of the buoyant force is directly proportional to the volume of the displaced fluid and its density. If an object is fully submerged, the displaced volume is equal to the object's total volume. If the object floats, it displaces a volume of fluid whose weight is equal to the object's own weight. This is why lighter objects can float in denser liquids, as they only need to displace a smaller volume of the denser liquid to achieve a buoyant force equal to their weight.

The term térfogatkiszorító is particularly relevant in fields such as naval architecture, where the displacement of a ship is a critical measure of its size and carrying capacity. It is also used in chemistry and physics when calculating densities or analyzing the properties of materials. Understanding the concept of displaced volume is essential for explaining why objects sink or float and for quantifying the forces involved.
