Veerõhu

Veerõhu, also known as hydrostatic pressure, is the force exerted by a fluid at rest due to gravity. It is the pressure that a fluid exerts on any surface of its container or on any object submerged within it. This pressure increases with depth, meaning that the deeper an object is in a fluid, the greater the pressure it experiences. This is because the weight of the fluid above the object presses down on it.

The formula for calculating hydrostatic pressure is P = ρgh, where P is the pressure, ρ (rho) is the density of the fluid, g is the acceleration due to gravity, and h is the depth of the fluid. This equation highlights that for a given fluid and gravitational acceleration, pressure is directly proportional to depth. For example, the pressure at the bottom of a swimming pool is significantly higher than at the surface.

Veerõhu is a fundamental concept in fluid mechanics and has numerous practical applications. It explains why dams are built with thicker bases than tops, as the water pressure is greatest at the bottom. It also plays a role in buoyancy, the phenomenon that allows objects to float or sink in a fluid. Submarines and divers must account for veerõhu when operating at different depths. Understanding veerõhu is crucial for designing anything that interacts with liquids, from aquariums to deep-sea exploration vehicles.
