DOI: 10.1615/AtoZ.w.weber_number

Weber number, We, is a dimensionless group that occurs in the analysis of bubble formation and other interfacial phenomena.

where ρ is fluid density, μ velocity, L dimension and σ interfacial surface tension. It represents the ratio of inertial force to surface tension force.

There are several alternative forms of Weber number, including the square root of the above expression.
