Equivalent Sand-Grain Roughness - an overview ...

In the nominally smooth (also know as hydraulically smooth) regime, sand-grain roughness has no effect, but other types of wall roughness may still cause a roughness effect (Colebrook 1939).More recently, the measured onset of roughness effects has been found to occur at k t + ∼ 9 (Flack et al., 2012), where k t is the peak-to-trough roughness height.
