HM 150.12A Vertical Flow From a Tank Teaching Equipment Fluid Mechanics Experiment Equipment
1. Equipment introduction
In the flow conditions in the pipeline, people are more concerned about the flow loss than the flow resistance. Although large resistance often means large losses, since they correspond to changes in momentum and energy respectively, their essences are different. The fluid produces both momentum loss and energy loss in the boundary layer. At this time, the resistance and loss change trends are consistent. But for the wake area, the momentum loss at the trailing edge of the object and at a certain distance behind it are basically the same, but the energy loss is quite different. In other words, the fluid only produces resistance on the surface in contact with the object. Once it leaves the object, it no longer produces resistance. However, the velocity loss in the wake area will continue to cause shearing downstream, and flow losses will continue to occur. Therefore, it is very necessary to study flow loss. In order to facilitate a more intuitive study of flow loss, we have manufactured a professional learning device, which can help us understand and learn flow loss. The HM 150.12A vertical flow device from a storage tank is used to study flow losses during discharge through an aperture to the outside environment. It can study losses at different flow rates.
