An Archimedes number, named after the ancient Greek scientist Archimedes, to determine the motion of fluids due to density differences, is a dimensionless number in the form

where:

g = gravitational acceleration (9.81 m/s²),
ρ_l = density of the fluid,
ρ = density of the body,
μ = fluid absolute viscosity.
