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.

Calculate the friction factor, Reynolds number, and visualize flow regimes on the Moody chart with our advanced Moody Chart Calculator. Ideal for fluid flow calculations in pipes.

A Moody Chart (or Moody Diagram) is used to estimate the friction factor for fluid flow in a pipe. The chart represents friction factor as a function of Reynolds number and the ratio between internal pipe roughness and pipe diameter, or relative roughness, ε/D.

The Moody chart or Moody diagram is a graph in non-dimensional form that relates the Darcy-Weisbach friction factor f D, Reynolds number Re, and relative roughness for fully developed flow in a circular pipe. It can be used for working out pressure drop or flow rate down such a pipe.

Dec 30, 2023 · How to use a Moody Chart (Moody Diagram) to determine friction factors in steady state pipe flow.

There are two definitions of the friction factor. The SI based friction factor is four times larger than the Imperial based friction factor. The Moody friction factor - λ (or f) - is used in the Darcy-Weisbach major loss equation. The coefficient can be estimated with the diagram below:
