Mean Velocity in Hydraulics and Waterworks Formulas
The Mean Velocity refers to the average speed at which fluid flows through a given cross-sectional area of a pipe or channel. And is denoted by V
mean
. Mean Velocity is usually measured using the Meter per Second for Speed. Note that the value of Mean Velocity is always negative.

FAQ
What is the Mean Velocity?
The Mean Velocity refers to the average speed at which fluid flows through a given cross-sectional area of a pipe or channel. Mean Velocity is usually measured using the Meter per Second for Speed. Note that the value of Mean Velocity is always negative.
Can the Mean Velocity be negative?
Yes, the Mean Velocity, measured in Speed can be negative.
What unit is used to measure Mean Velocity?
Mean 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 Mean Velocity can be measured.
