Friction Factors for Turbulent Flow in Pipes
It was the author's opinion that curves for determining values of the. friction factor f could be fitted to the hyperbolic cotangent of x, some function of . R, the Reynolds number. This is because coth x has an infinite value when x is equal to zero. As x increases, but remains of small magnitude, coth x decreases rapidly. As x increases further in value, the rate of decrease of coth x lessens until, for all practical purposes, coth x reaches unity when x is equal to, or exceeds, 3.5. On this basis two formulas are presented that permit the computation of the friction factor throughout the entire range of Reynolds numbers for turbulent flow in pipes.
