Graph of friction factor vs. reynolds number
In engineering, the Moody chart or Moody diagram (also Stanton diagram) is a graph in non-dimensional form that relates the Darcy–Weisbach friction factor fD, Reynolds number Re, and surface roughness for fully developed flow in a circular pipe. It can be used to predict pressure drop or flow rate down … See more In 1944, Lewis Ferry Moody plotted the Darcy–Weisbach friction factor against Reynolds number Re for various values of relative roughness ε / D. This chart became commonly known as the Moody chart or Moody diagram. It … See more Moody's team used the available data (including that of Nikuradse) to show that fluid flow in rough pipes could be described by four dimensionless quantities: Reynolds number, pressure loss coefficient, diameter ratio of the pipe and the relative … See more This formula must not be confused with the Fanning equation, using the Fanning friction factor $${\displaystyle f}$$, equal to one fourth the Darcy-Weisbach friction factor See more Friction loss Darcy friction factor formulae See more WebThe friction factor can now be calculated given values for thread radius , the thread injection velocity V , the eccentricity parameter as well as the pressure gradient-based …
