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.

Friction coefficient relates pipe roughness and Reynold number flow pattern if both are equal so both pipe have hydraulically same roughness.
