1. Product Introduction

1.1 Product Description

In the flow condition in the pipeline, people are more concerned about flow loss than flow resistance. Although in many cases, large resistance means large loss, but because they correspond to the change of momentum and energy respectively, their essence is different.
The fluid generates both momentum loss and energy loss in the boundary layer, and the change trend of resistance and loss is consistent. But for the wake zone, the momentum loss at the trailing edge of the object and at a certain distance behind it is basically the same, but the energy loss is quite different. In other words, the fluid only generates resistance on the surface in contact with the object, and once it leaves the object, it no longer generates resistance. However, the velocity loss in the wake zone will continue to shear downstream and continue to generate flow loss.
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 that can help us understand and learn about flow loss.
