- Forces encountered in flowing fluids include those due to inertia, viscosity, pressure, gravity, surface tension and compressibility.
These forces can be written as follows:
Reynolds number (Re):
- It is defined as the ratio of inertia force to viscous force.
Froude number (Fr):
- It is defined as the ratio of inertia force to gravity force.
Weber number (We):
- It is defined as the ratio of the inertia force to surface tension force.
Mach number (M):
- It is defined as the ratio of inertia force to velocity of sound.
