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 = 45 kg/m³
  • Velocity = 95 m/s
  • Length = 75 m
  • Surface Tension = 70 N/m

Solution

Substituting into Eq 1.1:

Result = (45 × 95 × 95 × 75) ÷ 70
