Abstract: The detailed measurement and analysis of the turbulent velocity distribution and friction loss data associated with the flow of water in a 100-mm diam corrugated plastic pipe is described. For the roughness geometry adopted, the friction factor - Reynolds number characteristic revealed a distinct peak in the initial stages of transition and fully turbulent flow region followed by a typical rising characteristic in the higher Reynolds number region. Velocity distributions were determined from pitot traverses and the resistance function evaluated therefrom correlates with a wall Reynolds number based on the true position of the logarithmic asymptote of the velocity profile for the fully rough zone of flow. The location of the asymptote was established with the use of a technique employed by Perry, Schofield, and Joubert in a study of rough wall boundary layers.
