The following Darcy Weisbach equation can be used to calculate the pressure drop in a pipe: Hf = f L v²/ 2gD. Components of the Equation. hf = Head loss in a pipe (m or ft) L = Pipe length (m or ft) V = velocity of the fluid inside the pipe (m/s or ft/s) D = pipe internal diameter (m or ft)
WebChoked flow is a compressible flow effect. The parameter that becomes "choked" or "limited" is the fluid velocity. Choked flow is a fluid dynamic condition associated with the venturi effect.When a flowing fluid at a given pressure and temperature passes through a constriction (such as the throat of a convergent-divergent nozzle or a valve in a pipe) into …
