| Abstract: | On the basis of analytic research and a large number of calculations a simpleand useful calcuating method for hydraulic resistance of pipe is developed. The calculating problem of implicit function in Colebrook-White formula has been solvedby the authors. The formulas and characteristics of resistance factor for industrialsteel and cast-iron pipes is given. |
