Identification of the hydraulic resistance coefficient for a pipeline section under unsteady flow regime
The hydraulic resistance coefficient of a linear segment of a pipeline is one of the characteristics of operating efficiency of main pipelines for hydrocarbon crude. The problem of the above mentioned coefficient identification is formulated and it is reduced to a class of finite-dimensional optimization problems. The effective numerical methods of finite-dimensional optimization of the first order are proposed for the solution of the problem. The results of the test calculations are discussed.
