Froude number
Froude number (Fr), in hydrology and fluid mechanics is a dimensionless quantity used to indicate the influence of gravity on fluid motion.
The Froude number is a ratio of inertial and gravitational forces. This is written as:
Froude number = Velocity of the fluid / √ (gravity acceleration * depth of flow)
The equation is
Fr = v / √ (g l)
We have:
Fr=Froude number
v= Velocity of fluid
l= Depth of flow
g=Gravitational acceleration
