Weber Number Calculator  

Density :
ρ = Weσ/v^{2}L
Velocity :
v= √Weσ/ ρL
Characteristic Length :
L = Weσ/ ρv^{2}
Surface Tension :
σ = ρv^{2}L/We
Where,
We = Weber Number,
ρ = Density,
v = Velocity,
L = Characteristic Length,
σ = Surface Tension.
Example:
Calculate the Weber Number for the given details.
Density (ρ) = 5 kg/m^{3}
Velocity (v) = 10 m/s
Characteristic Length (L) = 15 m
Surface Tension (σ) = 20 N/m
Solution:
Apply Formula:
We = ρv^{2}L/σ
Weber Number (We) = 375
