Zhipeng Duan, Auteur ; M. M. Yovanovich, Auteur ; Y. S. Muzychka, Auteur |The objective of this paper is to furnish the engineer with a simple and convenient means of estimating frictional pressure drop in ducts and the original physical behavior can be clearly reflected. Fully developed turbulent flow frictional pres[...]
