Definition

factor proportional to magnitude $F_{D}$ of the drag force (drag force) of a body moving in a fluid, dependent on the shape and speed $v$

(ISO 80000-3: Space and time) of a body:

$F_{D} = \frac{1}{2} C_{D} ρ v^{2} A$

where $ρ$ is mass density (mass density) of the fluid and $A$ is cross-section area (ISO 80000-3: Space and time) of the body

coefficient proportionnel à la norme $F_{D}$ de la traînée (drag force) d'un corps en mouvement dans un fluide, dépendant de la forme et de la vitesse $v$ (ISO 80000-3: Space and time) du corps :

$F_{D} = \frac{1}{2} C_{D} ρ v^{2} A$

où $ρ$ est la masse volumique (mass density) du fluide et $A$ est l'aire (ISO 80000-3: Space and time) de la section transversale du corps
