Technical Specification
Practical demonstration and visualization are essential elements of fluid flow study. The Drainage and Seepage Tank has been designed to make an experimental study of flow through permeable media. The supporting structure of the tank is made from painted mild steel while the sides of the tank are supported and sealed by a well proven method which allows free access to the interior and results in minimum sight obstruction. One side is of toughened glass to give good scratch-free visibility over a long period of use while the other is made of aluminum which permits the insertion of pressure tapping points as required. The ends of the tank are made of steel plate. Adjustable overflows are provided close to each end of the tank so that constant water levels may be maintained in each half of the tank. These may be lowered to a position close to the bed of the tank for some experiments to provide subsoil drainage. The equipment is self-contained, requiring only an initial fill with cold water and connection to the electricity supply. The sump tank can be emptied to a laboratory drain.
