A correction fluid is an opaque, usually white fluid applied to paper to mask errors in text. Once dried, it can be handwritten or typed upon. It is typically packaged in small bottles, with lids attached to brushes (or triangular pieces of foam) that dip into the fluid. The brush applies the fluid to the paper.
In nonideal fluid dynamics, the Hagen–Poiseuille equation, also known as the Hagen–Poiseuille law, Poiseuille law or Poiseuille equation, is a physical law that gives the pressure drop in an incompressible and Newtonian fluid in laminar flow flowing through a long cylindrical pipe of constant cross section.
Blasius boundary layer. In physics and fluid mechanics, a Blasius boundary layer (named after Paul Richard Heinrich Blasius) describes the steady two-dimensional laminar boundary layer that forms on a semi-infinite plate which is held parallel to a constant unidirectional flow. Falkner and Skan later generalized Blasius' solution to wedge flow ...
Here is a unit vector in the direction of the flow/current/flux. u = u ( r , t ) {\displaystyle \mathbf {u} =\mathbf {u} \left (\mathbf {r} ,t\right)\,\!} ϕ V = ∫ S u ⋅ d A {\displaystyle \phi _ {V}=\int _ {S}\mathbf {u} \cdot \mathrm {d} \mathbf {A} \,\!}
Tipp-Ex. Tipp-Ex is a brand of correction fluid and other related products that is popular throughout Europe. It was also the name of the German company ( Tipp-Ex GmbH & Co. KG) that produced the products in the Tipp-Ex line. While Tipp-Ex is a trademark name for correction products, in some countries it has become a genericised trademark: [1 ...
For a conduit flowing completely full of fluid at Reynolds numbers greater than 4000, it is expressed as: 1 f = − 2 log ( ε 3.7 D h + 2.51 R e f ) {\displaystyle {\frac {1}{\sqrt {f}}}=-2\log \left({\frac {\varepsilon }{3.7D_{\mathrm {h} }}}+{\frac {2.51}{\mathrm {Re} {\sqrt {f}}}}\right)}
In thermodynamics, the Volume Correction Factor (VCF), also known as Correction for the effect of Temperature on Liquid (CTL), is a standardized computed factor used to correct for the thermal expansion of fluids, primarily, liquid hydrocarbons at various temperatures and densities.
In fluid flow around a body with a sharp corner, the Kutta condition refers to the flow pattern in which fluid approaches the corner from above and below, meets at the corner, and then flows away from the body. None of the fluid flows around the sharp corner. The Kutta condition is significant when using the Kutta–Joukowski theorem to ...
Shallow-water equations, in its non-linear form, is an obvious candidate for modelling turbulence in the atmosphere and oceans, i.e. geophysical turbulence. An advantage of this, over Quasi-geostrophic equations, is that it allows solutions like gravity waves, while also conserving energy and potential vorticity.
In fluid dynamics, the Darcy–Weisbach equation is an empirical equation that relates the head loss, or pressure loss, due to friction along a given length of pipe to the average velocity of the fluid flow for an incompressible fluid. The equation is named after Henry Darcy and Julius Weisbach.
