Weber Number Calculator
The Weber number is termed as a dimensionless number in fluid mechanics which is often used in analysing fluid flows where there is an interface between two different fluids.
Table of Contents:
Formula
Weber Number :
We = ρv2L/σ
Density :
ρ = Weσ/v2L
Velocity :
v= √Weσ/ ρL
Characteristic Length :
L = Weσ/ ρv2
Surface Tension :
σ = ρv2L/We
Where,
We = Weber Number,
ρ = Density,
v = Velocity,
L = Characteristic Length,
σ = Surface Tension.
The Weber Number is especially used for multiphase flows with strongly curved surfaces.
Example:
Calculate the Weber Number for the given details.
Density (ρ) = 5 kg/m3
Velocity (v) = 10 m/s
Characteristic Length (L) = 15 m
Surface Tension (σ) = 20 N/m
Solution:
Apply Formula:
We = ρv2L/σ
Weber Number (We) = 375
