  2. Hydrostatics - Wikipedia

    en.wikipedia.org/wiki/Hydrostatics

    Fluid statics or hydrostatics is the branch of fluid mechanics that studies fluids at hydrostatic equilibrium [1] and "the pressure in a fluid or exerted by a fluid on an immersed body". [ 2 ] It encompasses the study of the conditions under which fluids are at rest in stable equilibrium as opposed to fluid dynamics , the study of fluids in motion.

  3. Pascal's law - Wikipedia

    en.wikipedia.org/wiki/Pascal's_law

    Pressure in water and air. Pascal's law applies for fluids. Pascal's principle is defined as: A change in pressure at any point in an enclosed incompressible fluid at rest is transmitted equally and undiminished to all points in all directions throughout the fluid, and the force due to the pressure acts at right angles to the enclosing walls.

  4. Hydrostatic equilibrium - Wikipedia

    en.wikipedia.org/wiki/Hydrostatic_equilibrium

    In fluid mechanics, hydrostatic equilibrium (hydrostatic balance, hydrostasy) is the condition of a fluid or plastic solid at rest, which occurs when external forces, such as gravity, are balanced by a pressure-gradient force. [1]

  5. Pressure prism - Wikipedia

    en.wikipedia.org/wiki/Pressure_prism

    Hydrostatic pressure is the pressure exerted by a fluid at rest – for example, on the sides of a swimming pool, a glass of water or the bottom of the ocean. Its value at any given location within the fluid is the product of the fluid density ( ρ ), the depth ( d ), and the forces applied by gravity ( g ) plus any background pressures, such ...

  6. Hydrostatic stress - Wikipedia

    en.wikipedia.org/wiki/Hydrostatic_stress

    A specialized case of hydrostatic stress contains isotropic compressive stress, which changes only in volume, but not in shape. [1] Pure hydrostatic stress can be experienced by a point in a fluid such as water. It is often used interchangeably with "mechanical pressure" and is also known as confining stress, particularly in the field of ...

  7. Archimedes' principle - Wikipedia

    en.wikipedia.org/wiki/Archimedes'_principle

    Archimedes' principle is a law of physics fundamental to fluid mechanics. ... bottom surface of the cube is the hydrostatic pressure at that depth multiplied by the ...

  8. Bernoulli's principle - Wikipedia

    en.wikipedia.org/wiki/Bernoulli's_principle

    It represents the internal energy of the fluid due to its motion. The hydrostatic pressure p is defined as =, with p 0 some reference pressure, or when rearranged as head: =. The term ⁠ p / ρg ⁠ is also called the pressure head, expressed as a length measurement. It represents the internal energy of the fluid due to the pressure exerted on ...

  9. Tait equation - Wikipedia

    en.wikipedia.org/wiki/Tait_equation

    In fluid mechanics, the Tait equation is an equation of state, used to relate liquid density to hydrostatic pressure.The equation was originally published by Peter Guthrie Tait in 1888 in the form [1]
