Abstract

The study is devoted to determining the value of the hydraulic resistance coefficient of a linear section of a pipeline. The problem is reduced to a problem of finite-dimensional optimization for whose solution we suggest to use the first-order numerical methods. The formulas are obtained for the components of the gradient of the objective functional in the space of parameters to be identified. The results of numerical experiments are presented.
