Gravitational Drinking Water Supply System Study / Hydraulic Behaviour Visualisation of a Water Distribution and Supply Network

Realistic implementation of a pump-fed drinking water supply system. This study bench enables work under highly realistic conditions on fluid dynamics concepts relevant to all types of industrial processes, particularly water conveyance. Learning Objectives: Determination of reference planes, piezometric lines, and energy lines for a given flow. Characterisation of pressurised flows during transient regimes. Water treatment by chlorination. Comparison of management systems for such an installation.
