How is the flow velocity in a circular pipe calculated?
Thread Content
Gas flows through an annular pipe; how is the flow velocity calculated? For example, for 20,000 Nm3/h of gas flowing through the annular gap in a pipe with an outer diameter of 100 and an inner diameter of 40, how is the flow velocity calculated?
Calculation in segments: the flow velocity varies in different pipe sections
Personally, I think it has to do with the flow area, and not much with the shape of the flow; or rather, unless the flow path is extremely unusual!
What is the pressure? It’s also related to stress
Yes, the problem shouldn’t be complicated: lol
Yes, yes, I forgot to consider this factor; I’m ashamed! :L
It is recommended to look at the chapters on fluid flow rates in Principles of Chemical Engineering; these values can be calculated
