Can someone please tell me where do we use the Weber number?
Can someone please tell me where do we use the Weber number? I know that we can calculate it using the formula:
We = rho*v^2*l/sigma, where We = Weber number, rho = density, v = velocity of fluid, l = char. length scale, and sigma is the surface tension.
However, I am not able to understand where this number can be used?
