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.

    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
