Note: Weber Number is dimensionless.

Weber Number formula:
   We = ρ * v2 * L / σ
   We:Weber Number, dimensionless
   ρ: Fluid Density, in Kg/m^3
   v: Fluid Speed (velocity), in meter/second
   L: Characteristic Length, in meter
   σ: Surface Tension, in N/m

The Weber number is named after Moritz Weber. It is used to analyse fluid flows when there is an interface between two different fluids. © 2017  Terms of Use | Home
