Laplace number : ウィキペディア英語版 | Laplace number
The Laplace number (La), also known as the Suratman number (Su), is a dimensionless number used in the characterization of free surface fluid dynamics. It represents a ratio of surface tension to the momentum-transport (especially dissipation) inside a fluid. It is defined as follows: : where: * σ = surface tension * ρ = density * L = length * μ = liquid viscosity Laplace number is related to Reynolds number (Re) and Weber number (We) in the following way: : ==See also==
* Ohnesorge number - There is an inverse relationship, , between the Laplace number and the Ohnesorge number. Category:Dimensionless numbers of fluid mechanics Category:Fluid dynamics
