Laplace number represents the ratio of surface tension to momentum- transport inside a fluid. it is used in the characterization of free surface fluid dynamics. show that the laplace number is dimensionless. the laplace number is expressed as: = / where σ = surface tension, rho = density , l = length and μ = liquid viscosity. the units of liquid viscosity are kg/(m. s) and for surface tension are n/m
