Archimedes number
An Archimedes number, to determine the motion of fluids due to density differences, is a number in the form
- <math>Ar = \frac{g L^3 \rho_l (\rho - \rho_l)}{\mu^2}<math>
Where
- g - gravity acceleration (9.81 m/s2)
- ρl - density of the fluid
- ρ - density of the body
- μ - fluid absolute viscosity
