Assessment of the impact of the adopted norm of specific water consumption on the efficiency of operation of pumping stations

The paper considers a sample of the actual specific water consumption of several closed hydraulic circuits accumulated over a long-term observation period. Using standard statistical methods, the types of distribution density function were determined and analytical expressions were obtained for the specific water consumption of the corresponding neighborhoods, followed by drawing on a summary graph and quantifying falling into the normalized range of specific water consumption in accordance with SP 31.13330.2021. The influence of the actual specific water consumption on the performance of pumping equipment, pumping water pumping stations is shown.
