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
Fluid Mechanics The inherent characteristic of an equal percentage valve relating flow rate 'q' with valve stem movement 'x' are described by the equation dq/dx = Kq² dq/dx = K.q dq/dx = K dq/dx = K/q dq/dx = Kq² dq/dx = K.q dq/dx = K dq/dx = K/q ANSWER DOWNLOAD EXAMIANS APP
