Weber Number Calculator

Calculate the Weber number using: $$ We = \frac{\rho\, v^2\, L}{\sigma} $$

* Enter the fluid density (kg/m³), flow velocity (m/s), characteristic length (m), and surface tension (N/m).

Step 1: Enter Parameters

Fluid Density, $ \rho $ (kg/m³):

e.g., 1000 kg/m³ for water

Flow Velocity, $ v $ (m/s):

e.g., 1 m/s

Characteristic Length, $ L $ (m):

e.g., 0.01 m

Surface Tension, $ \sigma $ (N/m):

e.g., 0.072 N/m for water at 20°C
