An algorithm is proposed for solving the problem of refining the drag coefficients in complex hydraulic nets in the presence of pressure probes in some intervals of the net. The algorithm enables the determination of the drag of net intervals at least for problems of small dimension. To find the drag coefficients in hydraulic nets with several hundreds of intervals and more an algorithm is required for solving large ill-conditioned systems of linear equations. One can also replace the system intervals with equivalent simpler intervals, thereby reducing concurrently the problem dimension and making the system of equations better conditioned.
