Web(3) is available and numerical tech- niques are used for obtaining the solution. For turbulent flow of Bingham fluids in smooth pipe, the famous implicit NPK (Nikuradse–Prandtl–Karman) equation is applicable [4] and can be deduced from Colebrook–White equation [5] under smooth pipe condition [6]. WebThe work of many others including Poiseuille, Hagen, Reynolds, Prandtl, Colebrook and White have contributed to the development of formulae for calculation of friction factors …
