WebThe Wikipedia article on "Darcy friction factor formulae" states “The Haaland equation is used to solve directly for the Darcey-Weisbach friction factor f for a full-flowing circular pipe. It is an approximation of the implicit Colebrook-White equation, but the discrepancy from experimental data is well within the accuracy of the data.” WebIt has been suggested that this article or section be merged into Frictional pressure drop.
