Fluid Mechanics In case of hydraulically smooth pipe, the resistance to flow depends only on the Reynolds number, whereas for a hydraulically rough pipe, the resistance to flow is governed by the relative roughness. Two pipes are said to have the same hydraulic roughness, when they have equal values of Friction co-efficient for flows at equal Reynold number All of these Relative roughness Absolute roughness Friction co-efficient for flows at equal Reynold number All of these Relative roughness Absolute roughness ANSWER DOWNLOAD EXAMIANS APP
