The technique of engineering calculation of perforation holes area which is variable along the length of the channel and provides steady fluid inflow along the path is developed in the article. It is based on previously obtained analytical solutions of differential equations describing the fluid motion in pressure perforated pipelines of a constant cross section. The use of such pipes in treatment plants will increase their efficiency. It is determined that the steady fluid inflow along the length of the pipe can be secured only by its non-steady walls perforation. The maximum perforation of the pipeline walls should be ensured at the initial sections of the channel, and the minimum – at their last sections. The corresponding graphs are built according to the formulas. Convenient empirical dependencies for determining the hydraulic friction coefficient and the coefficient of perforation holes discharge for the considered case are proposed. The results of the calculations according to the proposed method are confirmed by the results of experimental studies.
