Flow rate to velocity equation
WebFlow rate and velocity are related by [latex] Q=Av [/latex] where A is the cross-sectional area of the flow and v is its average velocity. The equation of continuity states that for … WebIn general, the friction factor itself is in turn a function of flow rate, thus making the whole flow equation an implicit one. For purposes of determining friction factor, it has been found that fluid flow may ... determine velocity as flow rate/area corrected to actual conditions to substitute for v. Conveniently, much
