INFLUENCE OF VALUE OF INPUT JETS INFLOW ANGLES ON NON-UNIFORMITY OF WATER INFLOW INTO PRESSURE PIPELINE-COLLECTORS ALONG PATH
Results of the experimental investigation of water inflow into a pressure pipe-collector (PC) depending on the value of the inflow angle b of the input jets are presented. The inner diameter of the experimental PC was of D=20.18 mm, and that of the output nozzles was of d=6.01 mm. The total length of the PC was 2494 mm, and its perforated part was of l = 1800 mm. The distances between the nozzles were equal to 180 mm. The water head H outside the PC was varied from 300 to 1600 mm. PCs with the inflow angles of jets of: 0o ; 45o ; 90o ; 135 o ; 180 o have been investigated.
