Material	Sizes (mm)	Roughness (mm)
Galvanized iron	15 - 100	0.20
PVC	15 - 200	0.005
Copper	15 - 100	0.003
Stainless steel	15 - 100	0.02
Concrete	150 - 3000	1.50
Asbestos cement	150 - 3000	0.50
Cast iron	15 - 100	0.26

Pipe roughness defines internal surface irregularities that cause hydraulic friction. It is critical for calculating head loss, sizing pumps, and ensuring efficient pressure maintenance across municipal water supply distribution networks.
