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 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.
Wite-Out dates to 1966, when Edwin Johanknecht, an insurance -company clerk, sought to address a problem he observed in correction fluid available at the time: a tendency to smudge ink on photostatic copies when it was applied. Johanknecht enlisted the help of his associate George Kloosterhouse, a basement waterproofer who experimented with ...
Liquid Paper products at The Women's Museum in Dallas, Texas. Liquid Paper is an American brand of the Newell Brands company marketed internationally that sells correction fluid, correction pens, and correction tape.
In fluid dynamics, Stokes' law is an empirical law for the frictional force – also called drag force – exerted on spherical objects with very small Reynolds numbers in a viscous fluid. It was derived by George Gabriel Stokes in 1851 by solving the Stokes flow limit for small Reynolds numbers of the Navier–Stokes equations .
A correction factor is also required for other more complex geometries, such as a shell and tube exchanger with baffles. Derivation [ edit ] Assume heat transfer [2] is occurring in a heat exchanger along an axis z , from generic coordinate A to B , between two fluids, identified as 1 and 2 , whose temperatures along z are T 1 ( z ) and T 2 ( z ) .
In thermal fluid dynamics, the Nusselt number ( Nu, after Wilhelm Nusselt [1] : 336 ) is the ratio of total heat transfer to conductive heat transfer at a boundary in a fluid. Total heat transfer combines conduction and convection. Convection includes both advection (fluid motion) and diffusion (conduction). The conductive component is measured ...
Faxén's law is a correction to Stokes' law for the friction on spherical objects in a viscous fluid, valid where the object moves close to a wall of the container. See also. Immersed boundary method; Notes
Q is the flow rate (m 3 /s) of the fluid flowing through the area A. The flux of fluid through A is q = Q/A. L is the length of the cylinder. Δp = p outlet - p inlet = p b - p a. = Δp/L = hydraulic gradient applied between the points a and b.
The Knudsen number ( Kn) is a dimensionless number defined as the ratio of the molecular mean free path length to a representative physical length scale. This length scale could be, for example, the radius of a body in a fluid. The number is named after Danish physicist Martin Knudsen (1871–1949).
