Pigott, [3] whose work was based upon an analysis of some 10, experiments from various sources. Nikuradse [5] were at the time too recent to include in Pigott's chart.

The chart's purpose was to provide a graphical representation of the function of C. Colebrook in collaboration with C.

White, [6] which provided a practical form of transition curve to bridge the transition zone between smooth and rough pipes, the region of incomplete turbulence. Head loss can be calculated using the Darcy—Weisbach equation in which the Darcy friction factor f D appears:. This formula must not be confused with the Fanning equation , using the Fanning friction factor f , equal to one fourth the Darcy-Weisbach friction factor f D:.

The Moody chart can be divided into two regimes of flow: One model for this relationship is the Colebrook equation which is an implicit equation in f D:.
