That dimensionless quantity is conceptually the ratio of inertial to viscous forces.
The ChiltonÂ–Colburn j-factor is an extension of a statement named for this man that relates the skin friction and heat transfer coefficients. That statement, which conceptually links momentum transfer to heat transfer, is his namesake "analogy." The laminar boundary layer thickness is inversely proportional to the square root of a quantity named for him. Empirical correlations between the friction factor and both roughness and a quantity named for this scientist are plotted on a (*) Moody diagram. Creeping flow occurs at very low values of a quantity named for him, which equals density times velocity times characteristic length divided by viscosity. That dimensionless quantity is conceptually the ratio of inertial to viscous forces. For 10 points, name this scientist whose namesake number predicts whether a flow is laminar or turbulent.
