WebThe Fanning friction factor is not the same as the Darcy Friction factor (which is 4 times greater than the Fanning Friction factor). The formula given is very similar to the Darcy … WebFanning friction factor pressure drop Friction is the major reason for pressure drop to take place. The friction will decrease the velocity of the flow of the fluid and also decreases the pressure as the fluid flows in the pipe. The pressure drop is directly proportional to the Fanning friction factor.
