Shear Velocity in Hydraulics and Waterworks Formulas

The Shear Velocity refers to the measure of the shear stress exerted by the fluid flow on the boundary, such as the bed of a river or the walls of a pipe. And is denoted by V_shear. Shear Velocity is usually measured using the Meter per Second for Speed. Note that the value of Shear Velocity is always positive.

FAQ

What is the Shear Velocity?

The Shear Velocity refers to the measure of the shear stress exerted by the fluid flow on the boundary, such as the bed of a river or the walls of a pipe. Shear Velocity is usually measured using the Meter per Second for Speed. Note that the value of Shear Velocity is always positive.

Can the Shear Velocity be negative?

No, the Shear Velocity, measured in Speed cannot be negative.

What unit is used to measure Shear Velocity?

Shear Velocity is usually measured using the Meter per Second[m/s] for Speed. Meter per Minute[m/s], Meter per Hour[m/s], Kilometer per Hour[m/s] are the few other units in which Shear Velocity can be measured.
