This must be realized to study and demonstrate potential flow. It must include a test channel where different rubber models can be pressured between two plates. The upper glass plate must be mobile in order to insert models. The lower one contains small holes to be connected to a water source or water sink. Several rubber models, such as circular, rectangle and airfoil, must be included in the basic unit. Streamlines around test models must be clearly shown by using a regulated flow of dye solution.
