Calculation of distribution drainage pipelines laid with a slope

Quite simple and easy-to-use analytical dependencies for calculation of the main hydraulic structural characteristics distribution drainage pipelines, laid with a certain slope, are presented. They proposed on basis analysis differential equations system, which consists variable mass hydraulics equation modified filtration equation, describes fluid motion in such pipelines. The solutions original system obtained under assumption neglecting term that takes into account effect flow rate variation along path. uses concept an infinitely long pipeline, is or, what same, inclined pipeline infinite capacity side surface walls. Series calculations pipelines at different slope values were carried out according to formulas. Corresponding graphic constructed clarity. It shown geometric pressure resistance factor generalized parameter A significantly affects design parameters pipes.
