Abstract
The utility model relates to a physical pressure demonstration device. The physical pressure demonstration device comprises an iron support; a T-shaped pipe is arranged on the lower part of the iron support; a nozzle is arranged in the T-shaped pipe; a high-level water tank is arranged on the upper part of the iron support; the high-level water tank and the nozzle are connected with each other through a connecting pipe; the T-shaped pipe is connected with a first wide-mouth bottle through a liquid level display pipe; the connecting pipe is connected with a second wide-mouth bottle through a drainage pipe; two sections of water flow test pipes having different diameters are arranged on the drainage pipe; pressure display pipes are arranged on the water flow test pipes; a second pipe clamp is arranged on the connecting pipe; a third pipe clamp is arranged on the drainage pipe; and the second pipe clamp is positioned on the lower part of the joint of the connecting pipe and the drainage pipe. When the physical pressure demonstration device is used, the first pipe clamp and the second pipe clamp are opened and water in the high-level water tank is sprayed out of the nozzle through the connecting pipe; under the action of a water flow sprayed out of the nozzle, the air flow speed in the T-shaped pipe is increased, the liquid levels in the wide-mouth bottles fall and the liquid level in the liquid level display pipe rises, so the idea that the air flow speed is higher and the pressure is lower is represented intuitively.
Description
Technical field
The utility model relates to a kind of physics and commonly uses teaching aid, relates to a kind of physics pressure apparatus for demonstrating specifically.
Background technology
In present middle school physics study, the student is when the concerning of study size of rate of flow of fluid and pressure size, more little for the big more pressure of rate of flow of fluid, the notion that the more little pressure of flow velocity is big more is because more abstract, the student is difficult for understanding to teacher's explanation, understanding for the ease of the student, the teacher explains usually at first theoretically, and then enumerate a plurality of real-life examples and help the student and understand, but still can not show to the student intuitively and illustrate, thereby can not make deep understanding of student and memory.
The utility model content
Problem to be solved in the utility model is at above problem, provides a kind of and can intuitively show the more little notion of the big more pressure of rate of flow of fluid, makes the student can profound understanding to this physical concept and a kind of physics pressure apparatus for demonstrating of memory.
For addressing the above problem, the technical scheme that the utility model adopted is: a kind of physics pressure apparatus for demonstrating, comprise iron stand, described iron stand bottom is provided with T type pipe, be provided with nozzle in the described T type pipe, described iron stand top is provided with elevated tank, described elevated tank is connected by connecting pipe with nozzle, described T type pipe is connected with first wide-necked bottle by liquid level charactron, described connecting pipe is connected with second wide-necked bottle by drainpipe, described drainpipe is provided with two sections current testing tubes that diameter is different, described current testing tube is provided with the pressure display tube, described connecting pipe is provided with second pipe clamp, and described drainpipe is provided with the 3rd pipe clamp, and described second pipe clamp is positioned at the bottom of connecting pipe and drainpipe junction.
A kind of concrete prioritization scheme, the top of described connecting pipe and drainpipe junction is provided with first pipe clamp.
A kind of concrete prioritization scheme, described T type pipe bottom is provided with low flush tank.
A kind of concrete prioritization scheme, described current testing tube is horizontally disposed with.
A kind of concrete prioritization scheme, described pressure display tube and current testing tube vertical connection.
The utility model is taked above technical scheme, have the following advantages: during use, first pipe clamp and second pipe clamp are opened, the water of elevated tank sprays from nozzle behind connecting pipe, because nozzle is positioned at T type pipe, under the effect of nozzle ejection current, air flow in the T type pipe is accelerated, so T type intraductal pressure reduces, under atmospheric effect, the liquid level in the wide-necked bottle will descend, and the liquid level in the liquid level charactron rises, thereby showed the more little notion of the big more pressure of gas flow rate intuitively, make the student to this physical concept can be deep understanding and memory.
Also first pipe clamp and the 3rd pipe clamp can be opened, liquid is through two current testing tubes that diameter is different, the liquid level of the pressure display tube on the bigger current testing tube of diameter is higher, the liquid level of the pressure display tube on the less current testing tube of diameter is lower, thereby showed the more little notion of the big more pressure of flow rate of liquid intuitively, make the student to this physical concept can be deep understanding and memory.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Accompanying drawing is the structural representation of a kind of physics pressure apparatus for demonstrating among the utility model embodiment.
