Fluid mechanics is a branch of physics that studies the laws of equilibrium and flow of fluids (liquids and gases).

: Whether flow properties at a point change over time.

: Gases are highly compressible, while liquids are often treated as incompressible for many engineering applications.

) : A dimensionless value used to predict flow patterns (laminar or turbulent).

: The fundamental partial differential equations that describe the motion of viscous fluid substances.

: The elastic-like force existing in the surface of a liquid at an interface. 2. Fluid Statics (Hidrostatika)

: Pressure applied to a confined fluid is transmitted undiminished to every part of the fluid and the walls of the container. Hydrostatic Pressure : Calculated as P0cap P sub 0 is the atmospheric pressure and is the depth.
