Flow velocity symbol
Webc or v are usually used as symbols for the average flow velocity. Often v is used for the local velocity, while c is used as a symbol for the mean velocity. The DIN 24260 provides the symbol v for the average speed. The average flow velocity is an important parameter when selecting the optimum pipe diameter for a new pipeline. WebNov 26, 2024 · Enter the average velocity of the flow. Let's pick 10 f t / s 10\ \mathrm{ft/s} 10 ft/s. And there it is, the first part of the calculations is done: the tool has worked as a volumetric flow rate calculator. We've …
