Mean velocity in Modes of Heat Transfer Formulas

Mean velocity is defined as the average velocity of a fluid at a point and over an arbitrary time T. And is denoted by u_m. Mean velocity is usually measured using the Meter per Second for Speed. Note that the value of Mean velocity is always positive.

FAQ

What is the Mean velocity?

Mean velocity is defined as the average velocity of a fluid at a point and over an arbitrary time T. Mean velocity is usually measured using the Meter per Second for Speed. Note that the value of Mean velocity is always positive.

Can the Mean velocity be negative?

No, the Mean velocity, measured in Speed cannot 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.
