V=mean velocity in the pipe D=pipe diameter Note Kinematic viscosity depends on the fluid temperature and can be calculated from the following formula = 497×106 (T+42.5)1.5 T is fluid temperature in Celsius Relative Roughness e(mm)=Roughness height (internal roughness of the pipe) and it depends mainly on the pipe material.pipe rough values - pumpfundamentalsPipe absolute roughness values (RMS) Material Absolute roughness (in x 10-3) Absolute roughness (micron or m x 10-6) Riveted steel1 36-360 915-9150 Concrete1 12-120 305-3050 Ductile iron2 102 2591 Wood stave1 3.6-7.2 91-183 Galvanized iron1 6 152 Cast iron asphalt dipped1 4.8 122
