NOUVELLE APPROCHE POUR LE DIMENSIONNEMENT DES CONDUITES CIRCULAIRES SOUS PRESSION

Abstract

The objective of this study is to propose a new approach for the calculation of turbulent flow in a circular pipe under pressure. This new approach is based in partly on Darcy-Weisbach and Colebrook-White relations, and on the other on a new model of reference. Explicit relations are proposed and the results obtained by application of those can be regarded as accurate. They apply in the interval of roughness for 0≤ /D≤5.10-2 and for all values of Reynolds number R>2300. The interest of the rough reference model proposed will serve as a basis for the design of pipes and canals that are the subject of this work.
