HM 150.09A Horizontal Flow From a Tank Vocational Training Equipment Hydrodynamics Laboratory equipment
1. Equipment introduction
Fluid dynamics considers the relationship between trajectory, outlet profile and outlet velocity during tank flow. These considerations have practical applications in hydraulic engineering or in the design of outfalls at the base of dams. HM 150.09A allows the user to study and visualize the profile of a water jet. Additionally, the shrinkage coefficient can be determined as a characteristic of different profiles. The experimental setup consisted of a transparent water tank, a point gauge, and a panel for visualizing the jet path. The water outlet of the tank is fitted with an interchangeable insert to facilitate inspection of individual openings. The unit comes with four blades of different diameters and profiles. To visualize the trajectory, the emitted water jet is measured by a point gauge consisting of a movable rod. The position of the measuring rod depends on the profile of the water jet. This produces a trace that is transferred to the panel. The tank contains an adjustable overflow and graduated scale. In this way, the liquid level can be precisely adjusted and accurately read. The experimental setup can be placed easily and securely on the work surface of the HM 150 basic module. The HM 150A supplies water and measures the flow rate. Alternatively, the experimental setup can be operated from the laboratory water supply.
