Weber Number

Theory & Logic

Theoretical Background

Physics describes the fundamental mechanism of the universe. The Weber Number is an essential tool for understanding Weber Number in quantitative terms. Calculate We = (ρv²L)/σ.

Mathematical Formulation

The relationship between the variables is governed by the following equation:

Result = (rho × v × v × l) ÷ sigma
Eq 1.1: Governing Formula

Variable Legend

Symbol Parameter Unit
rho Density kg/m³
v Velocity m/s
l Length m
sigma Surface Tension N/m

Practical Calculation Example

Problem

Calculating the result when:

  • Density = 40 kg/m³
  • Velocity = 25 m/s
  • Length = 90 m
  • Surface Tension = 20 N/m

Solution

Substituting into Eq 1.1:

Result = (40 × 25 × 25 × 90) ÷ 20
