Galileo Number

Galileo number ( \(Ga\) ) (dimensionless number) (also known as Galilei number) is a ratio of forces present in the flow of viscous fluids.  It is used in the momentum of heat transfer, viscous flow, thermal expansion.

Galilei Number FORMULA

\(\large{ Ga = \frac{ g \; \dot \;\;  l^3 \; \dot \;\; \mu^2 } { \rho^2 }   }\)         


\(\large{ Ga }\) = Galileo number

\(\large{ g }\) = gravitational acceleration

\(\large{ l }\) = characteristic length

\(\large{ \mu }\)  (Greek symbol mu) = viscosity

\(\large{ \rho }\)  (Greek symbol rho) = density
