Fluid Mechanics The pressure drop per unit length of pipe incurred by a fluid 'X' flowing through pipe is Δp. If another fluid 'Y' having both the specific gravity & density just double of that of fluid 'X', flows through the same pipe at the same flow rate/average velocity, then the pressure drop in this case will be Δp 2Δp Δp² Δp/2 Δp 2Δp Δp² Δp/2 ANSWER DOWNLOAD EXAMIANS APP

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 Relative roughness Absolute roughness All of these Friction co-efficient for flows at equal Reynold number Relative roughness Absolute roughness All of these Friction co-efficient for flows at equal Reynold number ANSWER DOWNLOAD EXAMIANS APP
