    Flux F through a surface, dS is the differential vector area element, n is the unit normal to the surface. Left: No flux passes in the surface, the maximum amount flows normal to the surface.

  3. Borda–Carnot equation - Wikipedia

    en.wikipedia.org/wiki/Borda–Carnot_equation

    ΔE is the fluid's mechanical energy loss, ξ is an empirical loss coefficient, which is dimensionless and has a value between zero and one, 0 ≤ ξ ≤ 1, ρ is the fluid density, v 1 and v 2 are the mean flow velocities before and after the expansion. In case of an abrupt and wide expansion, the loss coefficient is equal to one. [1]

  4. Fluid mechanics - Wikipedia

    en.wikipedia.org/wiki/Fluid_mechanics

    Fluid mechanics is the branch of physics concerned with the mechanics of fluids (liquids, gases, and plasmas) and the forces on them. [1]: 3 It has applications in a wide range of disciplines, including mechanical, aerospace, civil, chemical, and biomedical engineering, as well as geophysics, oceanography, meteorology, astrophysics, and biology.

  5. Fluid dynamics - Wikipedia

    en.wikipedia.org/wiki/Fluid_dynamics

    In physics, physical chemistry and engineering, fluid dynamics is a subdiscipline of fluid mechanics that describes the flow of fluids – liquids and gases.It has several subdisciplines, including aerodynamics (the study of air and other gases in motion) and hydrodynamics (the study of water and other liquids in motion).

  6. Bernoulli's principle - Wikipedia

    en.wikipedia.org/wiki/Bernoulli's_principle

    Bernoulli's principle is a key concept in fluid dynamics that relates pressure, density, speed and height. Bernoulli's principle states that an increase in the speed of a parcel of fluid occurs simultaneously with a decrease in either the pressure or the height above a datum. [1]:

  7. Reynolds number - Wikipedia

    en.wikipedia.org/wiki/Reynolds_number

    The Reynolds number is the ratio of inertial forces to viscous forces within a fluid that is subjected to relative internal movement due to different fluid velocities. A region where these forces change behavior is known as a boundary layer, such as the bounding surface in the interior of a pipe.

  8. Carreau fluid - Wikipedia

    en.wikipedia.org/wiki/Carreau_fluid

    The dynamics of fluid motions is an important area of physics, with many important and commercially significant applications. Computers are often used to calculate the motions of fluids, especially when the applications are of a safety critical nature.

  9. Flow velocity - Wikipedia

    en.wikipedia.org/wiki/Flow_velocity

    In many engineering applications the local flow velocity vector field is not known in every point and the only accessible velocity is the bulk velocity or average flow velocity ¯ (with the usual dimension of length per time), defined as the quotient between the volume flow rate ˙ (with dimension of cubed length per time) and the cross sectional area (with dimension of square length):
