Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Refer to Fig. 1 and Fig. 2, a kind of embodiment that the utility model is provided：A kind of fluid pressure and flow velocity relation one
Makeup is put, including central baffle 1 and bottom plate 5, and be adhesively fixed connection, bottom between the bottom of central baffle 1 and the upper surface of bottom plate 5
The upper end for the support base 6 that plate 5 is laid is fixed with the acrylic board 8 for being close to the table wall of central baffle 1, the inside of acrylic board 8
