Froude number is the ratio of inertial force to the gravitation force.
\(\text{Froude }\!\!~\!\!\text{ number}=\text{ }\!\!~\!\!\text{ }\sqrt{\frac{\text{Inertia force }\!\!~\!\!\text{ }}{\text{Gravitational force }\!\!~\!\!\text{ }}}\)
Froude number has the following applications:
- Used in cases of river flows, open-channel flows, spillways, surface wave motion created by boats
- It can be used for flow classification
Important Points
\(\text{Reynold's number}=\frac{\text{Inertia force}}{\text{Viscous force}}\)
\(\text{Euler }\!\!~\!\!\text{ number}=\sqrt{\frac{\text{Inertia force}}{\text{Pressure force}}}\)
\(\text{Weber }\!\!~\!\!\text{ number}=\sqrt{\frac{\text{Inertia force}}{\text{Surface Tension force}}}\)
\(\text{Mach }\!\!~\!\!\text{ number}=\sqrt{\frac{\text{Inertia force}}{\text{Compressibility force}}}\)
