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 Relative roughness All of these Absolute roughness Friction co-efficient for flows at equal Reynold number Relative roughness All of these Absolute roughness ANSWER DOWNLOAD EXAMIANS APP
Fluid Mechanics Reynolds number for water flow through a tube of I.D. 5 cm is 1500. If a liquid of 5 centipoise viscosity and 0.8 specific gravity flows in the same pipe at the same velocity, then the pressure drop will Remain same Data insufficient to predict pressure drop Increase Decrease Remain same Data insufficient to predict pressure drop Increase Decrease ANSWER DOWNLOAD EXAMIANS APP
