The Froude Number for Rectangular Channels The Froude Number for flow in an open channel is defined as: Fr = V2/gy, where V, y, and g are the average velocity, depth of flow, and ... WebThe Froude Number can be expressed as. Fr = v / (g h m) 1/2 (1) where. Fr = Froude number. v = velocity (m/s) g = acceleration of gravity (9.81 m/s 2) h m = hydraulic mean depth or characteristic length (m) The Froude Number is relevant in fluid dynamic problems where the weight (gravitational force) of the fluid is an important force.
The jump starts where the flow is just critical and Froude number is equal to 1.0. The Froude number has been used to study trends in animal locomotion in order to better understand why animals use different gait patterns [15] as well as to form hypotheses about the gaits of extinct species.
