The friction factor obtained from Moody chart is mainly the “Darcy Friction Factor”. So if we are taking about Moody Friction factor or Moody Friction Chart we are mainly referring … WebAnother common friction factor is the Fanning friction factor, which is one-fourth of the Darcy friction factor. To take advantage of the simplification for determining the Darcy friction factor by using a Moody chart, oftentimes it is possible to find a Moody chart for the Fanning friction factor .
Fanning vs darcy friction factor
Did you know?
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. WebThe friction factor is a dimensionless number, which is used in the mechanical energy balance to relate the head loss or pressure loss along a given length of pipe to the average velocity of a viscous fluid.. There are two friction factors: The Darcy friction factor and the Fanning friction factor .The Darcy friction factor is 4 times the value of the Fanning …
