What is Hydraulic Resistance in Vacuum Sewage Systems about?

The document summarizes experimental research into hydraulic resistance on lifts in pipelines for a vacuum sewage system. Measurements were taken of pressure drops on lifts in pipelines with diameters of 65mm, 90mm, and 110mm and with interface valve opening times of 6, 9, and 12 seconds. Empirical formulas were derived based on the results to calculate hydraulic resistance on lifts in vacuum sewage system pipelines based on underpressure values and valve opening times. The research helps address a lack of
