What siphon phenomenon? Why does siphoning occur?

The energy of water is made up of potential energy (gravitational potential energy), pressure energy, and kinetic energy. For a simple analysis, in a uniform siphon pipe, because the kinetic energy is constant, if the viscosity of the water is ignored (ignoring the friction loss), the potential energy and pressure energy should be conserved. At the top of the siphon pipe, the potential energy is maximum, the pressure energy is minimal, and the pressure is less than atmospheric pressure (negative pressure).

Therefore, if you make a hole in the top of the siphon pipe, the water will not come out, but the air will go in, the pressure will increase, and the siphon will be interrupted. The pressure at both ends of AB is basically equal to atmospheric pressure, and the potential energy of the inlet A end is greater than the potential energy of the outlet B, so the energy that pushes the siphon flow ** is the water level difference between the inlet and outlet of the siphon pipeline, which can be said to be the water level difference that pushes the flow of water. Even with this push, the siphon does not start automatically, and a negative pressure condition must first be created in the pipe.

Once the flow begins, no additional power is required.

The siphon phenomenon is caused by the gravitational force and potential energy difference between liquid molecules, that is, the pressure difference between the water column is used to make the water rise and then flow to a low place. Since the nozzle water surface is subjected to different atmospheric pressures, the water will flow from the highest-pressure side to the lower-pressure side, until the atmospheric pressure on both sides is equal, and the water surface in the container becomes the same height, and the water will stop flowing.

The siphon principle is the principle of the communicator, and the pressure applied to the liquid in a closed container is equal everywhere. The siphon is filled with water, there is no gas, the water level at the incoming end is high, and the water outlet is closed with the palm of the hand or other objects. At this time, the pressure in the tube is equal everywhere.

After everything is settled, open the water outlet, although the atmospheric pressure on both sides is equal, but the water level at the incoming end is high, and the pressure is strong, pushing the incoming water to flow out of the outlet.

Siphon phenomenon refers to the phenomenon of liquid flow due to altitude difference under the action of atmospheric pressure. After filling an inverted U-shaped tubular structure, the high end of the opening is placed in a container filled with liquid, and the liquid in the container continues to flow out through the siphon to a lower position.

Siphon phenomenon. Siphoning is a fluid physical phenomenon that can be used to pump liquids without the help of a water pump.

The essence of siphon is due to the pressure of the liquid and the pressure of the atmosphere.

The siphon phenomenon has applications in life, such as fish tanks, water tanks, etc.

The siphon principle is to use the force phenomenon of the height difference of the liquid level to fill a tube structure with an inverted U-shape, and then place the high end of the opening in a container filled with liquid, and the liquid in the container will continue to flow out through the siphon to a lower position.

In the 1st century B.C., a peculiar siphon was created. In fact, siphoning is not entirely caused by atmospheric pressure, but can also occur in a vacuum.

The force that makes the liquid rise is the cohesive force of the molecules between the liquids, and when the siphon phenomenon occurs, because the liquid flows out of the tube than the liquid flows into the tube, the gravity on both sides is unbalanced, so the liquid will continue to flow in one direction, and the higher the liquid flows into the tube, the lower the pressure.

If the liquid rises from a very high tube, the pressure will be reduced to such a point that bubbles (made up of air or other gases) will be formed in the tube, and the height of the siphon will be determined by the formation of bubbles.

Because the bubbles disconnect the liquid, the force between the gas molecules at both ends of the bubble is reduced to 0, thus destroying the siphon effect, so the tube must be filled with water. At normal atmospheric pressure, the siphon works better than in a vacuum, because the atmospheric pressure on both nozzles increases the pressure inside the entire siphon.

Extended Materials. The principle of siphon is applied to modern buildings, and the rainwater drainage system of the building roof was initially solved, and at the beginning of the research, a full-pipe pressure flow system was adopted, which made a major breakthrough in the rainwater drainage system of the piped roof. The siphon principle has been applied in building drainage, municipal drainage, water conservancy engineering and other aspects.

Siphon financial theory believes that technical analysis can solve the situation that fundamental analysis fails due to the use of inside information to make profits, such as a country using tension to affect commodities to make venture capital profits, which is completely possible in a modern society with highly developed financial informatization.

International economic integration has formed a market of size that can accommodate the wealth of the country, if you use inside information arbitrage, it is sometimes very difficult to judge in the fundamentals, and the technical side solves this shortcoming, technical analysis is not omnipotent, but independent fundamental analysis without technical analysis is obviously unable to avoid many unknown events.

For example, if a military dispute region decides to hold peace talks, if this plays an important role in the stability of the international society, and the international market is enough to accommodate the country's large hedging funds, it is entirely possible for the countries in the region to use the market to carry out risk-amplifying transactions for profit.

It is difficult to grasp the progress of the event from a fundamental analysis alone, but if it is analyzed from a technical perspective, it is possible to draw a correct judgment from the relevant market data.

Why does siphoning occur? From a physical point of view, due to the gravitational attraction and potential energy (gravitational potential energy) difference between the liquid molecules, the liquid will flow from the side with high pressure to the side with low pressure, a phenomenon called siphon effect, also known as siphon phenomenon. Although the atmospheric pressure is the same on both sides of the pipeline, due to the gravitational potential energy difference, the water on the higher side will flow downward under the action of gravity until the atmospheric pressure and water pressure on both sides of the pipeline are equal, and the water will stop flowing.

Using the siphon phenomenon, people can pump out the water inside the container. [1]

At present, the siphon principle has been applied in modern building drainage, municipal drainage, water conservancy engineering, etc.

Hello, to produce the siphon phenomenon: 1. The liquid outflow end of the elbow must be lower than the inflow end; 2. The elbow must be filled with liquid; 3. No air can enter the inside of the elbow (a very small amount of bubbles is fine, but too much will not work); 4. The liquid inflow end must be kept below the liquid level continuously; 5. The liquid must be able to flow freely, and there can be no valves or plugs to block the pipe. If you want to eliminate the siphon, you just need to destroy one of these conditions.

Siphoning is a hydrodynamic phenomenon that can draw liquids without the help of a pump. The liquid in the higher position fills an inverted U-shaped tubular structure (called a siphon) and opens in the lower position. In this structure, the liquid pressure difference between the two ends of the tube can push the liquid past the highest point and discharge to the other end, mainly by gravitational force to make the siphon work.

Siphon phenomenon: 1. Relying on atmospheric pressure, the phenomenon of using a curved tube to lead the trapped liquid from the high liquid level to the low place. The siphon phenomenon has many applications, such as in Henan and Shandong in China, where water from the Yellow River is often diverted across the river embankment to irrigate farmland.

2. Siphonage is the use of the force phenomenon of the height difference of the liquid level to fill the liquid with an inverted U-shaped tubular structure, and place the high end of the opening in a container filled with liquid, and the liquid in the container will continue to flow out through the siphon to a lower position.

Siphon phenomenon is a physical phenomenon that people often use in life, siphon is the application of the interaction force phenomenon of the height difference of the liquid level, so that the liquid is filled with an inverted U-shaped tubular structure, and the two ends are inserted into two containers with different liquid level heights, then the liquid in the container will continue to flow through the siphon to the low liquid level.

The phenomenon of siphoning is actually a scientific phenomenon caused by the combined effect of liquid pressure and atmospheric pressure, and it is often confused with the principle of a communicator. Most of the toilets in people's homes also use the siphon principle, because this kind of toilet is not only efficient and has a strong sewage discharge capacity, but also has low noise when used, which is very suitable for various important work places and homes.
