Vedelikurõhul
Vedelikurõhul, often translated as hydrostatic pressure, is the pressure exerted by a fluid at rest due to gravity. This pressure increases with depth within the fluid. Imagine being at the bottom of a swimming pool; you can feel the weight of all the water above you pushing down. This is a direct result of vedelikurõhul. The formula for 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.
The concept of vedelikurõhul is fundamental in understanding many natural phenomena and engineering applications. For instance,
The direction of vedelikurõhul is always perpendicular to any surface it acts upon. This means that at
