Weber Number

The Weber number is defined as the dimensionless number of ratio of inertial force to surface tension force.

Symbol: We

Measurement: NAUnit: Unitless

Note: Value should be greater than 0.

Formulas to find Weber Number

Density

Density of a material shows the denseness of that material in a specific given area. This is taken as mass per unit volume of a given object.

Symbol: ρ

Measurement: DensityUnit: kg/m³

Note: Value should be greater than 0.

Formulas to find Density

Velocity of Fluid

Velocity of Fluid is a vector quantity (it has both magnitude and direction) and is the rate of change of the position of an object with respect to time.

Symbol: V

Measurement: SpeedUnit: m/s

Note: Value should be greater than 0.

Formulas to find Velocity of Fluid

Length

Length is the measurement or extent of something from end to end.

Symbol: L

How to Evaluate Weber Number?

Weber Number evaluator uses Weber Number = ((Density*(Velocity of Fluid^2)*Length)/Surface Tension) to evaluate the Weber Number, The Weber Number formula is defined as dimensionless number in fluid mechanics that is often useful in analysing fluid flows where there is an interface between two different fluids, especially for multiphase flows with strongly curved surfaces. Weber Number is denoted by We symbol.

How to evaluate Weber Number using this online evaluator? To use this online evaluator for Weber Number, enter Density (ρ), Velocity of Fluid (V), Length (L) & Surface Tension (σ) and hit the calculate button.

FAQs on Weber Number
