= Dimensionless numbers of fluid mechanics
{wiki=Category:Dimensionless_numbers_of_fluid_mechanics}

Dimensionless numbers in fluid mechanics are quantities that are formulated as ratios of different physical properties, enabling the comparison of different physical phenomena without being affected by the units of measurement. These numbers help in the study of fluid flow, heat transfer, and mass transfer by simplifying the analysis and identifying the relative importance of various forces acting on a fluid within a system.
