reflection factor karvand-e bâztâb Fr.: facteur de réflexion The ratio of total flux that is reflected from a surface to the incident flux. Also called reflectance, reflectivity. → reflection; → factor. |
scale factor karvand-e marpel Fr.: facteur d'échelle Math.:
A number which scales, or multiplies, some quantity. In the equation
y = Cx, C is the scale factor for x. C is also the
coefficient of x, and may be called the constant of proportionality of
y to x. |
Stokes friction factor karvand-e mâleš-e Stokes Fr.: facteur de friction de Stokes For the translational motion of a spherical body moving in a → viscous fluid, the proportionality factor between the uniform flow velocity far from the sphere and the drag force, provided no-slip boundary condition and small → Reynolds numbers: f = 6πηR, where η is the Reynolds number and R radius of the sphere. |
