Comparison of Explicit Relations for Calculating Colebrook Friction Factor in Pipe Network Analysis Using h-based Methods
Abstract
Although many explicit correlations have already been presented as alternatives to implicit Colebrook–White (C–W) formula, performances of C–W-based relations in pipe network analysis have not been investigated. In this study, 56 explicit relations available in the literature were implemented in the analysis of four water distribution networks while the benchmark solution is computed considering the implicit C–W formula. In the numerical experiment, these pipe networks were solved using three different h-based methods including h-based Newton–Raphson method, finite element method, and the gradient algorithm. In each scenario, one of these explicit relations was considered in the process of analyzing water networks. According to the obtained results, 15 explicit relations face the convergence problems which were identified as unreliable equations. Moreover, 15 explicit equations, which were successfully performed in analyzing all sample networks with the closest results to that of the benchmark solution, were introduced as the most accurate ones. Moreover, as many scenarios outperform those of the outdated explicit equation used for the same purpose in professional hydraulic solvers such as EPANET and WaterGEMS, it was recommended they be replaced with one of the explicit equations with higher accuracy. Finally, the achieved results demonstrate that the equation selected for computing Darcy–Weisbach friction factor has an inevitable impact not only on the accuracy but also on the convergence of pipe network analysis.
