WebFeb 2, 2011 · For turbulent flow, the Fanning equation gives: (7) where l is the length of the vapor passageway, f is Fanning friction factor (0.079/Re v 1/4 for 2100 < Re v < 10 5), V v is the vapor velocity and D v the diameter of the vapor passageway; and where Re v is the Reynolds number for vapor flow.
WebFeb 2, 2011 · In this case, the friction factor of the Fanning equation can be calculated using the Hagen-Poiseuille equation (see Poiseuille Flow). (4) For turbulent flow, both … This friction factor is one-fourth of the Darcy friction factor, so attention must be paid to note which one of these is meant in the "friction factor" chart or equation consulted. Of the two, the Fanning friction factor is the more commonly used by chemical engineers and those following the British convention. The formulas below may be used to obtain the Fanning friction factor for common applications.
