Weber Number

Weber number is proportional to { (inertial force) / (surface tension force) } and is used in momentum transfer in general and bubble/droplet formation and breakage of liquid jets calculations in particular. It is normally defined in one of the following forms :

 

or

 

Where:

gc

=

Dimensional constant

G

=

Mass velocity

D

=

Characteristic length

rho

=

Density

sigma

=

Surface tension

V

=

Velocity
