Integral absolute roughness for main supply pipes:

For main supply lines the following typical values can be recommended.

These values take account of secondary losses due to pipe connections and sedimentation.

Integral absolute roughness for distribution networks:

For distribution networks the following typical values can be recommended.

These values take account of secondary losses due to valves, junctions and house connections.
