The problem of hydraulic calculation of pressure distribution pipelines

Most production technologies require a uniform flow path of liquid from pressure distribution pipelines. To achieve this goal, it is proposed to introduce polymer additives into the or use converging pipelines with continuous longitudinal slot in wall. reduce uneven operation pipeline during discrete dispensing, cylindrical output rotary nozzles lateral orthogonal entry jet nozzle. The problem lack methods for accurate hydraulic calculation Adequate are based on differential equations. Finding exact solution equation fluid motion variable rate perforated urgent, because still does not exist. available take account only right angles separation jets pipeline. These assumption that coefficient friction and resistance outlets constant along flow. A method takes change values these coefficients kinematic physical characteristics outside also taken account. accuracy calculating value water distributed has been experimentally verified. error consumption by assuming unchanged reaches 18.75 %. According method, exceed 6.25 However, both suitable design pipelines, provided straight. Taking 90° 360° angle will expand scope methods.
