Galileo Number

Galilei Number ( \(Ga\) ) (dimensionless 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

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

Where:

\(Ga\) = Galileo Number

\(g\) = gravitational acceleration

\(l\) = characteristic length

\(\nu\) (Greek symbol nu) = viscosity

\(\rho\) (Greek symbol rho) = density
