How This Is Calculated



$$ We = \frac{ \rho v^2 L}{ \sigma } $$ where:

We   =   Weber Number   (Dimensionless)

ρ   =   Fluid Density  (kg/m³)

v   =   Flow Velocity  (m/s²)

L   =   Characteristic Length   (m)

σ   =   Surface Tension   (N/m)


Assumptions



  • The fluid is incompressible.
  • The fluid is homogeneous.
  • Steady flow conditions.
  • Surface tension is constant.
