E x

Definition

quotient of buoyancy force and inertial force in moving fluids due to density differences for gas bubbles rising in a liquid, expressed by

$E x = \frac{g d}{v^{2}} (1 - \frac{ρ_{b}}{ρ})$ ; where

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

$d$ :: is diameter (ISO 80000-3: Space and time) of bubbles,

$v$ :: is speed (ISO 80000-3: Space and time) of bubbles,

$ρ_{b}$ :: is mass density (ISO 80000-4: Mechanics) of bubbles, and

$ρ$ :: is mass density (ISO 80000-4: Mechanics) of the liquid

quotient de la poussée d'Archimède par la force d'inertie dans des fluides en mouvement en raison de différences de masse volumique pour des bulles de gaz s'élevant dans un liquide, exprimé par:

$E x = \frac{g d}{v^{2}} (1 - \frac{ρ_{b}}{ρ})$ ; où

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

$d$ :: est le diamètre (ISO 80000-3: Space and time) des bulles;

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

$ρ_{b}$ :: est la masse volumique (ISO 80000-4: Mechanics) des bulles; et

$ρ$ :: est la masse volumique (ISO 80000-4: Mechanics) du liquide
