Is it true that the average flow velocity across a cross-section is not, in most cases, the actual flow velocity at that cross-section?
It is correct that the average flow velocity across a cross-section is, in most cases, not the actual flow velocity at that cross-section
It depends on what needs to be calculated; in water treatment, specific details are required based on the type of filler used
This statement is correct; the average value is not the true value.
Yes, the average flow velocity should be determined by measuring the flow rate over a certain period of time during a stable phase, and then calculated based on the theoretical relationship between flow rate and cross-sectional area! It’s not really a representation of tassels!
The end face is curved; the flow velocity is usually different at different distances from the center. An average value is taken during calculations, as mentioned in the principles of chemical engineering
