Weber Number Solution

STEP 0: Pre-Calculation Summary

Formula Used

Weber Number = ((Density*(Velocity of Fluid^2)*Length)/Surface Tension)
We = ((ρ*(V^2)*L)/σ)
This formula uses 5 Variables

Variables Used

Weber Number - The Weber number is defined as the dimensionless number of ratio of inertial force to surface tension force.
Density - (Measured in Kilogram per Cubic Meter) - 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.
Velocity of Fluid - (Measured in Meter per Second) - 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.
Length - (Measured in Meter) - Length is the measurement or extent of something from end to end.
Surface Tension - (Measured in Newton per Meter) - Surface Tension is a word that is linked to the liquid surface. It is a physical property of liquids, in which the molecules are drawn onto every side.

STEP 1: Convert Input(s) to Base Unit

Density: 997.3 Kilogram per Cubic Meter --> 997.3 Kilogram per Cubic Meter No Conversion Required
Velocity of Fluid: 101.6 Meter per Second --> 101.6 Meter per Second No Conversion Required
Length: 3.5 Meter --> 3.5 Meter No Conversion Required
Surface Tension: 72.75 Newton per Meter --> 72.75 Newton per Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

We = ((ρ*(V^2)*L)/σ) --> ((997.3*(101.6^2)*3.5)/72.75)

Evaluating ... ...

FAQ

What is 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 and is represented as We = ((ρ*(V^2)*L)/σ) or Weber Number = ((Density*(Velocity of Fluid^2)*Length)/Surface Tension). 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, 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, Length is the measurement or extent of something from end to end & Surface Tension is a word that is linked to the liquid surface. It is a physical property of liquids, in which the molecules are drawn onto every side.

How to calculate 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 is calculated using Weber Number = ((Density*(Velocity of Fluid^2)*Length)/Surface Tension). To calculate Weber Number, you need Density (ρ), Velocity of Fluid (V), Length (L) & Surface Tension (σ).
