摘要：The battle of background leakage estimate (BLE)
in water supply networks has been the subject of discussion in
the last years. This paper aims to investigate the effect of pipe
materials with particular reference to their impact on the BLE
in looped water supply networks using a graph-based integrated
hydraulic model. In the applications, the hydraulic modelling
was carried out through steady-state flow modelling. The model
was demonstrated on a water supply network derived from the
literature. The results obtained evidence the influence of pipe
materials on the background leakage estimation. The effect is
more pronounced on very smooth and new cast iron or welded
steel pipe while the least effect on BLE is observed when oil
cast iron and bricks is considered.
