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 f D, 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 such a pipe.

Before choosing a formula it is worth knowing that in the paper on the Moody chart, Moody stated the accuracy is about ±5% for smooth pipes and ±10% for rough pipes. If more than one formula is applicable in the flow regime under consideration, the choice of formula may be influenced by one or more of the following:
If the value of the friction factor is 0.064, then the Darcy friction factor is plotted in the Moody diagram. Note that the nonzero digits in 0.064 are the numerator in the formula for the laminar Darcy friction factor: f D = 64 / Re . If the value of the friction factor is 0.016, then the Fanning friction factor is plotted in the Moody ...
This was originally produced to describe the Moody chart, which plots the Darcy-Weisbach Friction factor against Reynolds number. The Darcy Weisbach Formula f D {\displaystyle f_{D}} , also called Moody friction factor, is 4 times the Fanning friction factor f {\displaystyle f} and so a factor of 1 4 {\displaystyle {\frac {1}{4}}} has been ...
Lewis Ferry Moody (5 January 1880 – 18 April 1953 [1]) was an American engineer and professor, best known for the Moody chart, a diagram capturing relationships between several variables used in calculating fluid flow through a pipe.
