Moody Diagram • 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 such a pipe. • One of the most widely used methods for evaluating the friction factor employs the Moody diagram
Reynold Number Turbulent (Re > 4000) Transition ( Re 2000 to 4000) Laminar (Re < 2000)
