This report is the summary of a literature survey and analytical study performed by the Armour Research Foundation for NEPA on the subject of the effect of turbulence promotion on forced convection heat transfer and fluid friction.

This monograph is intended to furnish the engineer up-to-date, practical information for accurately estimating the friction losses in large concrete, steel, and wood-stave pipes running full steady flow conditions. It summarizes experimental information otained through field measurements and large-scale laboratory experiments which the Bureau of Reclamation has compled from worldwide sources over a period of years. Charts are presented for obtaining friction factors for concrete pipe, continuous-interior, full-riveted and spiral-riveted steel pipe, and wood-stave pipe. These will assis the designer in predicting the behavior of a particular conduit.
