WebbWhat is friction factor a function of? The friction factor is found to be a function of the Reynolds number and the relative roughness. Experimental results of Nikuradse (1933) … WebbThe 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. Greater the value of Friction factor greater will be the pressure drop against the ends of pipe.

WebbThe frictional losses depend on the type of the flow (laminar or turbulent) and pipe elements (valves, elbows, tees, etc.). A common approach to characterization of frictional losses is to use the Fanning friction factor f defined as the friction force per unit surface area divided by the kinetic energy per unit volume ( ρv2/2).
