fluidstatik
Fluidstatik, commonly called hydrostatics, is the branch of fluid mechanics that analyzes fluids at rest. It studies how pressure is distributed inside a stationary fluid, how pressure depends on depth, and the resultant forces on boundaries and submerged bodies. The standard framework assumes a continuous, incompressible fluid in a uniform gravitational field, with boundaries that may exert normal (perpendicular) pressures.
The central equation is the hydrostatic equilibrium: dP/dz = rho g, where P is pressure, z is vertical
Buoyancy: An object submerged in a fluid experiences an upward buoyant force equal to the weight of
Common applications include barometry and manometry, calibration of measuring devices, analysis of water columns in pipes,
