Overview

The Weber number ( $We$ ) is a dimensionless number comparing inertial forces to surface tension forces. It is important in droplet formation, bubble dynamics, and free surface flows.

Variables

Symbol	Description	Unit
$We$	Weber number	—
$\rho$	Fluid density	kg/m³
$v$	Flow velocity	m/s
$L$	Characteristic length	m
$\sigma$	Surface tension	N/m

Formula

$We = \frac{\rho v^2 L}{\sigma}$
