Abstract

This paper presents a method for estimating a hydraulic resistance multiplier to enable approximate values of friction coefficients to be calculated for turbulent flows in noncircular channels of arbitrary shape using correlations developed for the circular pipe. Unlike most other methods, no preknowledge on the flow channels, such as the laminar shape factor or characteristic length, is required. Good agreement between predictions using the new method and experiments was achieved.
