Definition

EN

relation between viscous forces and gravity forces for particles falling in a fluid, expressed by

S t k 3 = v v / ( g l 2 ) ; where

v :: is characteristic speed (ISO 80000-3: Space and time) of particles,

v :: is kinematic viscosity (ISO 80000-4: Mechanics) of the fluid,

g :: is acceleration of free fall (ISO 80000-3: Space and time), and

l :: is length (ISO 80000-3: Space and time) of fall

FR

relation entre les forces visqueuses et les forces de pesanteur pour des particules tombant dans un fluide, exprimée par:

S t k 3 = v v / ( g l 2 ) ; où

v :: est la vitesse caractéristique (ISO 80000-3: Space and time) des particules;

v :: est la viscosité cinématique (ISO 80000-4: Mechanics) du fluide;

g :: est l'accélération due à la pesanteur (ISO 80000-3: Space and time); et

l :: est la longueur (ISO 80000-3: Space and time) de chute
