The hydraulic parameters of the flushing nozzle are determined depending on the pressure and flow rate of
water: the speed and force of the stream of water flowing out of the nozzle; the number and size of the nozzle nozzles. New design solutions for flushing nozzles are presented, which increase the efficiency of cleaning drainage pipelines. Comparative characteristics of the parameters of the applied and new design solutions of flushing nozzles are given.
