Webb14 apr. 2024 · Slurry infiltration has strong influence on the slurry pressure transfer, which is important for slurry shields. In our previous study, we have studied the filter cakes and the infiltration process. However, the filter of slurry by soil and the relation between infiltration and soil particles were untouched there. In this study, some experiments … WebbWhen making calculations for a slurry pump for a certain flow, the desired flow velocity (V) must be compared to the critical velocity (Vc) for the slurry and the pipe system in question. As the figure below shows, the ideal velocity (marked green) is immediately above the critical velocity but with a margin for the extreme cases that can arise.
