Resembling, flowing in, or forming torrents: torrential mountain streams; a torrential downpour. 2. Resulting from the action of fast-flowing streams: torrential erosion. 3. Flowing or surging abundantly; wild: torrential applause.
Thereof, why is the Froude number important?
The Froude number can be interpreted as the ratio of the inertial to gravity forces in the flow. When the Froude number is less than one, the flow velocity is smaller than the speed of a disturbance wave traveling on the surface. Flow is considered to be subcritical(tranquil flow). Gravitational forces are dominant.
What is the Weber number?
The Weber Number is a dimensionless value useful for analyzing fluid flows where there is an interface between two different fluids. The Weber Number is the ratio between the inertial force and the surface tension force and the Weber number indicates whether the kinetic or the surface tension energy is dominant.
