Abstract
Results of experimental investigation of the influence of Reynolds criterium \( Re_{D} \) on the non-uniformity in the work of pressure collector-pipeline (CPs) for different values of the angle \( \beta \) of jet inflow into the fluid stream in CP are presented. The angle \( \beta \) was assigned the following values: \( 0^{o} \); \( 4 5^{o} \); \( 9 0^{o} \); \( 1 3 5^{o} \); \( 1 8 0^{o} \). The value of Reynolds criterion \( Re_{D} \) was varied within the range from 5211 to 28321. In has been found that the non-uniformity of distribution of the working heads in the CP and those of water inflow into the CP along the path decreased with the increase in the Reynolds criterion \( Re_{D} \). By means of variation of the values of the angle \( \beta \), the reduction of non-uniformity of the working heads distribution along the CP was achieved up to 44.49%, and that of water inflow into the CP along the path up to 9.07% (as compared to the case of orthogonal jet inflow into the main stream of collector-pipeline).
