...' The first warning against such a simplistic assumption was given by Sarpkaya 1–2 in l976. Since then numerous experiments have been conducted and it has been generally shown that roughness (a) increases tube diameter, projected area, displaced volume and hence the hydrodynamic loading; (b) increases both...
