Most middle school students are now learning pressure-stricken knowledge.,This piece of knowledge belongs to the physical examination of the senior high school entrance examination,Higher points,The test type is very wide,And most of the comprehensive application of mechanical knowledge,So a difficult point belonging to the senior high school entrance examination,Middle school students are encountered when they encounter such complex problems,It is often a headache。Especially when pressure and buoyancy、pulley、When the lever is integrated into a piece,Its difficulty is almost the highest peak of junior high school physics.。

About pressure knowledge,Junior high school physics mainly tells two types of pressure knowledge:

First, quantitative learning“Solid pressure”as well as“Static fluid production”;

Second, qualitative learning“Pressure generated by flowing fluid”。

(connecting a brass water tube to a swamp cooler)In these two types of pressure knowledge,The former is the most important、Most difficult、Upper questions。The latter is a more interesting life physics phenomenon。

Today we pass a very interesting physical phenomenon,Let's talk about a living application problem in this chapter.。

(connecting a brass water tube to a swamp cooler)Many middle school students have seen a very fire in short video of mobile phones.“Hiro fountain”,But most of the middle school students don't understand“Hiro fountain”Physical principle,Three containers can be continuously formed in the fountain with pipelines.?so amazing!

Is there any very complicated physical principle that is contained there??

We uncoven by the following junior high school physics“Hiro fountain”Mysterious veil。

We saw,So-called“Hiro fountain”In fact, it is from three containers.,Three tubes consisting of。Two containers are sealed,A container opening。We analyze the start of liquid flow.,Due to the containeraContainercBelow,therefore,APipelineaContainercContainer forms a certain vertical height difference,Therefore there is a certain pressure difference,so,Water willaDown in the containerccontainer,ResultingcThe water in the container gradually increases,In turncIncreased air pressure of space above the container,andcWithbConnect,thereforebThe pressure on the container becomes large,due toBThe vertical height of the pipe is less thanAVertical height of the pipe,sobThe pressure on the container is greater than the outside air pressure andBThe pressure generated by the tube,ThusbUnder the action of air pressure in the containerBPipe mouth with water!

so,To increase the height of the fountain,likebAir volume in the container,That is, the internal pressure is unchanged.,It only needs to reduce the external pressure to increaseBPoor pressure difference,That is to say only need to decreaseBThe vertical height of the pipe can increase the height of the fountain。

This seems to be,This question is not difficult,The key is to analyze the physical reasons for clear water flow.!

There is a problem now.,What will the fountain will happen if this device has long??

Smart middle school students, please explain。

The following column link《Eight sets of senior high school tests》Incident summarizes almost all senior high school students、Easy-tolerant point、Demarrow!For the middle and lower reaches of students,Is the tool for improvement,For excellent students,It is the most practical and most efficient information of the physical learning method of the senior high school entrance examination.!
