Flow of water in curved pipes

Abstract

Preliminary Experiments .—The author has for several years been engaged in experimentally investigating the resistance to the flow of fluids in metal pipes, both straight and curved. In order to study the effect of change of curvature, several experiments have been made on the flow of water in flexible pressure tubing with thick walls—a composite of rubber and canvas—the inner portion being red rubber surrounded by canvas, the canvas being covered on the outside with grey rubber. Dimensions of tube:—Outside diameter 0⋅81 cm.; inside diameter 0⋅3684 cm. (calculated from the volume of the tube.)
