Be able to calculate a value of the moody friction factor for given re and εd using the moody friction factor equations.

How to use moody diagram. However there are some good resources on the web which covers this. It can be used to predict pressure drop or flow rate down such a pipe. Try the engineering toolbox moody diagram also good old wikipedia has extensive coverage moody chart w.

Si based moody diagram. Moody diagram for given re and εd. The coefficient can be estimated with the diagram below.

Both the reynolds number and relative roughness are unitless values when computed correctly therefore the moody chart is unitless so the same chart applies to us customary and si unit systems. If the flow is transient 2300 re 4000 the flow varies between laminar and turbulent flow and the friction coefiicient is not possible to determine. In engineering 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 surface roughness for fully developed flow in a circular pipe.

How to use a moody chart june 13 2015 a moody chart is commonly used by engineers to calculate the darcy weisbach friction factor which is then in turn used to calculate headpressure loss due to friction in pipes.
