Fluid flow through pipe experiences resistance due to viscosity, fluid turbulence and pipe surface roughness. Surface roughness is a major contributor to flow resistance. Roughness resistance (friction factor) calculations have required a tedious procedure to determine flow regime. The new simple and explicit criteria presented can be used to easily determine flow regime.
Introduction. For analyzing steady-state Newtonian fluid flow in pipe, the Darcy Weisbach equation, Eq. 1 is most commonly used. It provides the necessary relation between head loss due to surface resistance, fluid properties and pipe geometry as:
Where, f is the coefficient of
