ühtlusujuvus

ühtlusujuvus, also known as uniform buoyancy, is a principle in naval architecture and fluid dynamics. It describes a condition where a vessel floats in such a way that its weight is perfectly balanced by the buoyant force acting upon it. This means that the submerged volume of the vessel displaces a volume of water whose weight is equal to the total weight of the vessel itself, according to Archimedes' principle.

Achieving ühtlusujuvus is crucial for a ship's stability and seaworthiness. When a vessel is in a state of ühtlusujuvus, it will float at a specific, stable waterline. Deviations from this state can occur due to changes in the vessel's weight, such as the loading or unloading of cargo, the consumption of fuel or stores, or the accumulation of water. Understanding and managing ühtlusujuvus is essential for safe navigation and operation.

The concept is often discussed in relation to ballast, which is weight added to a vessel to control its buoyancy and stability. By carefully adjusting ballast, ship operators can ensure that their vessel maintains the desired state of ühtlusujuvus under various operating conditions. This principle is fundamental to the design and operation of all types of watercraft, from small boats to large ocean liners.
