High Accurate Explicit Solution for the Determination of Conduit Height

摘要

The objective of this work is to propose a new approach to dimensioning of the conduits partially or totally filled. To dimension the conduit, the wetted section and the wetted perimeter have to be expressed under the forms A = αH~2 and P = βH. The study is based on the relationships universally known of the Darcy-Weisbach and of Colebrook-White. In this study, the new developed approach leads to an explicit solution and the ensuing results can be compared to the different exiting models. The maximum relative error obtained of the 80% calculated values does not exceed 0.25%. What enables us to say that this approach adapts well to manual and computing calculations. It was found that this new contribution is more accurate than the most equations available literature.
