Weber Number Calculator
Weber number calculator is used to calculate the Weber number. This calculator also finds the other values, if the weber number is given. It will give the solution with steps.
What is weber's number?
Weber's number describes the tendency of a fluid to form droplets or to flow as a continuous stream. In the study of fluid dynamics, particularly the dynamics of droplets, sprays, and other fluid flows with surface tension effects, the Weber number is frequently utilized.
Formula:
We = (ρ)*(v2) *(L) / σ
Here,
- ρ is density
- v is velocity
- L is a characteristic length
- σ is the surface extension
How to calculate weber's number?
Example 1:
Determine Weber number if density= 12, velocity = 18, length = 32 , surface tension = 43.
Solution:
Given data:
ρ = 12, v = 18, L = 32, σ = 43, We =?
Formula:
We = (ρ)*(v2) *(L) / σ
Use the given values in the formula
We = (12) *(182) *(32) / 43
We = (12) *(324) *(32) / 43
We = 124416 / 43
We = 2893.4 z
Example 2:
Determine the weber number when density = 14, velocity = 23, length = 13, surface tension = 44.
Given data:
ρ = 14, v = 23, L = 13, σ = 44, We =?
Formula:
We = (ρ)*(v2) *(L) / σ
Use the given values in the formula
We = (14) *(232) *(13) / 44
We = (14) *(529) *(13) / 44
We = 96278 / 44
We = 2188.14 z
