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________?
ARelative roughness
BAll A., B. & C.
CFriction co-efficient for flows at equal Reynold number
DAbsolute roughness
Correct answer
C. Friction co-efficient for flows at equal Reynold number
Explanation
The correct answer is Friction co-efficient for flows at equal Reynold number.
