The Moody chart is a graph in non-dimensional form that relates the Darcy-Weisbach friction factor fD, 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

Darcy-Weisbach Friction Factor The momentum equation is dependent on f, the Darcy-Weisbach friction factor that is dependent on Reynolds number (Re) and relative roughness. The Moody diagram provides a chart of friction factor compared with Re for different relative roughness levels. An RTTM must...
(e.g. m3/s). The Moody friction factor (f) is used in theDarcy-Weisbach major loss equation. Note that for laminar flow, f is independent of e. However, you must still enter an e for the program to run even though e is not used to compute f. Equations can be found inDiscussion...

In addition to allowing users to directly determine the Moody friction factor or calculate pressure loss, the Moody chart is a valuable tool for determining many other kinds of information about a plumbing system. Using this information in this diagram, plumbers can estimate flow rate and pressure...
