Abstract

A bernoulli principle research device, is characterized in that: comprise coin piece and the plate of becalming, described in becalm on the side of plate and have the circumferential notch that holds described coin piece, the plate thickness of becalming at described circumferential notch place is not less than the thickness of described coin piece.The described plate of becalming can be cardboard or PVC plate.The plate of becalming can avoid gas to apply the power to pop-up from coin bottom, gets rid of the interference of other factors, and scientific spirit when study practical work is asked, gets a real idea of the relation between pressure and flow velocity.

Description

Bernoulli principle research device
Technical field
The utility model relates to a kind of Physical Experiment apparatus, particularly bernoulli principle research device.
Background technology
Between Study of Fluid pressure and flow velocity, the experiment appliance of relation is more now, be mostly the special instruments used for education in school laboratory, but for student, after wanting to go home, also can find equipment, meet the desire of probing into of descending oneself, just very difficult, lack a kind of equipment and be easy to get, the experimental program of can large area popularization carrying out.
Utility model content
The purpose of this utility model is: provide a kind of equipment to be easy to get, the bernoulli principle research device of can large area popularization carrying out, is beneficial to students and is in and also can tests.
The technical scheme that the utility model adopts is: a kind of bernoulli principle research device, it is characterized in that: comprise coin piece and becalm plate, on the side of the described plate of becalming, have the circumferential notch that holds described coin piece, the plate thickness of becalming at described circumferential notch place is not less than the thickness of described coin piece.
The described plate of becalming can be cardboard or PVC plate.
Adopt after said structure, the plate of becalming is placed on desktop edge, coin is placed in the circumferential notch of the front edge of board of becalming, and mouth is blown forward with strength facing to coin upper horizontal ground, can be observed coin and upwards takeoffs.Because the plate resistance of becalming has been kept off wind and has been blown into from coin bottom, avoided gas to apply the power to pop-up from coin bottom, coin top air velocity is accelerated, gas pressure intensity reduces, and coin bottom air pressure is substantially constant, so upper and lower pressure official post coin has been subject to the power making progress, coin is upwards takeoff, explanation is in fluid, and the fast local pressure of flow velocity is little, and the slow local pressure of flow velocity is large.
The beneficial effects of the utility model are: cardboard or PVC plate easily find, and also conveniently have scissors or blade to cut in the above or cut out the circumferential notch that holds coin, for each student is in, do the condition of having created of testing.The becalm setting of plate, also allow students association analyze, and design avoid the interference of other factors, learning science man spirit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A ˊ cut-open view of Fig. 1;
In figure: 1 plate of becalming, 2 breach, 3 coin pieces.
Embodiment
As shown in Figure 1, have the circumferential notch 2 that holds coin piece 3 on the side of the plate 1 of becalming, the plate thickness of becalming at breach 2 places is not less than the thickness of coin piece 3.The plate 1 of becalming can be made with cardboard or PVC plate.
