 Hello @Kremella

The Weber number is the ratio of the deforming inertial forces and the stabilizing cohesive forces acting on liquids that are flowing through a fluid medium. Physically, it represents the relative importance of the fluid's inertia compared to its surface tension. One critical application of Weber number is in the area of spray atomization. Weber number is often used to characterize the atomizing quality of a spray, and the droplet size in emulsions.
