Fluid Mechanics A 2" gate valve fitted in a pipe is replaced by a similar globe valve. Pressure drop in gate valve was Δp. For the same discharge, the pressure drop across globe valve is Δp² Δp > Δp < Δp Δp² Δp > Δp < Δp 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 Friction co-efficient for flows at equal Reynold number Absolute roughness Relative roughness All of these Friction co-efficient for flows at equal Reynold number Absolute roughness Relative roughness All of these ANSWER DOWNLOAD EXAMIANS APP
