Definition

quotient of gravitational forces and capillary forces for fluids in narrow pipes, expressed by

$C a = d^{2} ρ g / γ$ ; where

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

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

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

$γ$ :: is surface tension (ISO 80000-4: Mechanics) of the fluid

quotient des forces de gravitation par les forces capillaires pour des fluides dans des tubes étroits, exprimé par:

$C a = d^{2} ρ g / γ$ ; où

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

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

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

$γ$ :: est la tension superficielle (ISO 80000-4: Mechanics) du fluide
