FAQ

What is Fanning friction factor?
The Fanning friction factor is a dimensionless number used in studying fluid friction in pipes. This friction factor is an indication of the resistance to fluid flow at the pipe wall and is represented as ffanning<=f/4 or Fanning friction factor=Darcy friction factor/4. Darcy friction factor is denoted by f. Its value depends on the flow's Reynolds number Re and on the pipe's relative roughness ε / D. It can be obtained from Moody's chart.
