B g

Definition

quotient of drag force and gravitational force for a body moving in a fluid, expressed by

$B g = \frac{c_{D} ρ v^{2}}{l g ρ_{b}}$ ; where

$c_{D}$ :: is drag coefficient (drag coefficient) of the body,

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

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

$l$ :: is characteristic length (ISO 80000-3: Space and time),

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

$ρ_{b}$ :: is mass density (ISO 80000-4: Mechanics) of the body

quotient de la traînée par la force de gravitation pour un corps se déplaçant dans un fluide, exprimé par:

$B g = \frac{c_{D} ρ v^{2}}{l g ρ_{b}}$ ; où

$c_{D}$ :: est le coefficient de traînée (drag coefficient) du corps;

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

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

$l$ :: est la longueur caractéristique (ISO 80000-3: Space and time);

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

$ρ_{b}$ :: est la masse volumique (ISO 80000-4: Mechanics) du corps

Notes

The characteristic length, $l$ , is the body's volume divided by its cross-sectional area.

La longueur caractéristique, $l$ , est le quotient du volume du corps par l'aire de sa section droite.
