Abstract
Measurements made to determine friction and roughness coefficients for three different surfaces in the Apalachia Tunnel of the Tennessee Valley Authority are described in this paper. The sections tested were an 18-ft steel pipe coated with bituminous paint, an 18-ft concrete-lined tunnel, and an unlined rock tunnel of 20-ft and 22-ft nominal diameters. Discharges during the tests varied from 975 to 3,210 cu ft per sec. Methods of reducing the data are described and the results are presented in terms of f and n in the Weisbach and Manning equations, respectively. Also, the surfaces are described in detail and illustrated so that their respective friction and roughness coefficients may be applied to other similar surfaces.
