Abstract
The utility model relates to a device for demonstrating the relationship between fluid pressure and flow velocity. The device is characterized in that the device comprises an inverted T-shaped support, a larger-diameter transparent pipe arranged on the vertical surface of the support, a smaller-diameter transparent pipe connected with the two ends of the larger-diameter transparent pipe, and a U-shaped transparent pipe pressure gauge arranged at the two side lower ends of the larger-diameter and the smaller-diameter transparent pipes and filled with a colored liquid; and the larger-diameter and the smaller-diameter transparent pipes and the U-shaped transparent pipe pressure gauge are glass pipes or plastic pipes. The device adopts simple instruments to scientifically and visually demonstrate the relationship between the fluid pressure and the flow velocity to the students, and enables the students to know that: the larger the flow velocity of the fluid is, the smaller the pressure of the fluid is, and contrarily the smaller the flow velocity of the fluid is, the larger the pressure of the fluid is.
Description
Technical field
The utility model relates to a kind of instruments used for education, relates in particular to the instrument that concerns between a kind of pressure of demonstrating fluid and the flow velocity.
Background technology
Is there what kind of relation between the pressure of fluid and the flow velocity on earth? this is the simplest problems only common people.But accepting the student of knowledge for one, be appreciated that it is not a nothing the matter.A kind ofly can reflect the pressure of liquid and the instrument of the relation between the flow velocity intuitively so need,, their relation clearly can be presented in face of the student by demonstration.
Summary of the invention
The utility model fundamental purpose is: by fluid pressure and flow velocity relation demonstration device, make the student understand relation between flow rate of fluid and the pressure intuitively.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of fluid pressure and flow velocity relation demonstration device, it is characterized in that: have support, thick transparent tube is installed on the support, two ends in thick transparent tube are connected with thin transparent tube, are connected with the piezometer of the U-shaped transparent tube that look liquid is housed in the lower end, both sides of thick, thin transparent tube.
Described thick transparent tube, thin transparent tube and piezometer can be glass tube or plastic tube.
Described support is the inverted T-shaped structure, and transparent tube (comprising thick transparent tube, thin transparent tube and piezometer) is installed on the vertical plane.
The vertical plane of described support is the transparent body.
Therefore, the utility model adopts simple instrument, can science intuitively the pressure of fluid and the relation demonstration of rate of flow of fluid be seen to the student, allows students ' understanding: the pressure of the big more fluid of flow rate of fluid is just more little, otherwise the flow rate of fluid pressure of hour fluid more is just big more.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Embodiment
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment:
Fluid pressure as shown in Figure 1 and flow velocity relation demonstration device, has support 5, support is an inverted T-shaped, thick transparent tube 1 is installed on the vertical plane of support, two ends in thick transparent tube have been connected with thin transparent tube 2, connect the piezometer 4 of the U-shaped transparent tube that colored liquid is housed in the lower end, both sides of thick, thin transparent tube.The piezometer of described thick, thin transparent tube and U-shaped transparent tube all adopts glass to make.
During demonstration, when air-flow 3 supports the continuous thin glass tube that passes through again to the raw glass pipe with certain pressure from one, the speed of air-flow just from large to small, look liquid is equipped with in " U " shape piezometer the inside, be used for showing the pressure size on both sides, piezometer shows that the liquid level that links to each other with the raw glass pipe is low, and the liquid level height that links to each other with thin glass tube illustrates that big more its pressure of gas velocity is more little.Otherwise also set up.
