The friction-reducing properties of fiber suspensions were investigated. Fibers of asbestos, glass, and acrylic were found to greatly reduce the turbulent-flow resistance of both aqueous and nonaqueous suspending fluids. Pipe-flow and rotating-disk experiments show that fibers having the smallest diameter, and substantial length-to-diameter ratio gave the most friction reduction at the smallest weight concentration of fiber. An asbestos fiber gave 65 percent friction reduction in a small pipe-flow apparatus and 48 percent in the rotating-disk equipment (both being the maximum obtainable in the devices) at a suspension concentration of 500 ppm.
