The discharge-weighted average velocity of streamflow is proposed as an alternative to the more commonly used areaweighted average for uses where frictional energy losses are evaluated. Using experimental data from Mink Brook, NH, and data published by Marchand et al. (USGS Open File Report 84-733,

Abstract
A simple friction factor has been devised to characterize the frictional properties of textile materials. The friction factor enables universal comparisons among different textile materials. A poly(methyl methacrylate) sled has been used as a standard friction substrate to characterize the friction of a woven cotton fabric. The influence of the velocity of testing on the frictional characteristics has been studied in detail with the novel friction factor. This study elaborates the relationship between the speed of testing and the new fabric friction factor. ยฉ 2004 Wiley Periodicals, Inc. J Appl Polym Sci 92: 2420โ2424, 2004
