What is the siphon method and what does the siphon method mean

Siphon principle Siphon principle: It 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.

Siphoning is a physical phenomenon, for example, now you have two basins, one on the table, one on the ground, the basin on the table has water, there is no water on the ground, you want to make the water in the basin on the table to the basin on the ground without moving the two basins, you can use the siphon method, with a pipe, fill with water, one end in the basin of the table, one end in the basin on the ground, the water in the basin on the table will be siphoned into the basin on the ground, which can actually act on the basin that cannot be moved, the dam is direct.

The principle of siphoning is to use the pressure difference. That is, the pressure difference of the water column is used to make the water rise and then flow to a low place. Since the water surface of the nozzle is subjected to different atmospheric pressures, the water will flow from the high-pressure side to the low-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 phenomenon is used to quickly pump out the water in the container. Of course, gravity also plays an important role in the siphoning process.

Three conditions must be met to utilize the siphon principle:

1. Fill the tube with liquid first.

2. The height of the highest point of the pipe from the water surface of the container shall not be higher than the height of the water column supported by atmospheric pressure.

3. The water surface of the water outlet must be lower than that of the upper container. In this way, the downward pressure (atmospheric pressure of adding water) to the outlet sheet is greater than the upward atmospheric pressure. Ensure the outflow of water.

Siphon principle, fill the tube with water and plug the hole at one end and put it in the fish tank, one end outside, and release the hole with both hands at the same time, because the drop water will flow out, suck off the fish feces and dirt at the bottom of the tank, suck off one-third of the water in the tank, and then inject the treated new water.

Siphoning is a phenomenon that uses the force of the height difference between the liquid level to fill a tube structure with an inverted U-shape, and then places the high end of the opening in a container filled with liquid, and the liquid in the container continues to flow out of the lower opening through the siphon.

The essence of siphon is due to the pressure of the liquid and the pressure of the atmosphere. Therefore, according to Pascal's law p= gh, the liquid pressure in the left tube of the device is less than the liquid pressure of the right tube, in addition, there is atmospheric pressure at point B and point C, and the atmospheric pressure is shown to be low and high, but the difference between the atmospheric pressure between point B and C can be ignored in relation to the calculated height of the earth's atmospheric pressure. So, then the pressure at the left end of A is greater than the pressure at the right end of A, and the water moves in one direction under the combined action of atmospheric pressure and liquid pressure.

Special reminder: This is not a communicator, the concept of a communicator is an instrument that is connected at the upper end and the lower end. If there is no atmospheric pressure, only liquid pressure, then the water in the pipe will be bounded by point A, the left end will flow to the left, the right end to the right, and a vacuum layer is formed in the middle.

In the 60s of the last century, several scientists in Sweden applied the principle of siphon to modern buildings, and initially solved the rainwater drainage system of the building roof. The siphon principle has been applied in building drainage, municipal drainage, water conservancy engineering and other aspects.

Siphoning is the use of the liquid level height difference force phenomenon, after filling the liquid into 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 will continue to flow out through the siphon to a lower position, the essence of the siphon is caused by the liquid pressure and atmospheric pressure.

Siphonage is a phenomenon that uses the force of the difference in liquid level to fill a tube structure with an inverted U-shape, and then places the high end of the opening in a container filled with liquid, and the liquid in the container continues to flow out through the siphon to a lower position. From Su Shi's "Dongpo Zhilin" in the Song Dynasty. The essence of siphon is due to the pressure of the liquid and the pressure of the atmosphere.

The Chinese have long understood how to apply the principle of siphoning. The siphon made by the principle of siphon is called "Zhuzi", "Biti", "Thirsty Wu" or "Mountain Dragon" in ancient China. At the end of the Eastern Han Dynasty, thirsty black for irrigation appeared.

Ethnic minorities in the southwest region drink alcohol with a long bamboo tube that bends its knots, which is also a physical phenomenon of siphoning.

Financial applications

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 countries in the region to use the market to carry out risk-amplifying transactions for profit, if it is difficult to grasp the progress of the event from fundamental analysis alone.

However, if you analyze it from a technical perspective, you can draw a correct judgment from the relevant market data. In practical application, the siphon theory has different understandings of various actual investment varieties of investment, and the understanding of paper and physical investment is that long-term holding will obtain reliable returns.

Due to the limited reserves, and the continuous processing and use and the increase of new demand, the actual demand gap including the first mineral reserves will increase, and at the same time, the limited resource consumption will drive the **** up. Siphon theory has three aspects of understanding of margin trading: first.

1. Venture capital. Clause.

Second, the first product arbitrage. Clause.

3. Product hedging.

The energy of water is composed of potential energy (gravitational potential energy), pressure energy, kinetic energy, and the flow velocity of a body of water flowing in a pipe of the same radius is the same in all sections. In a homogeneous siphon pipe, since the kinetic energy is constant, if the viscosity of the water is ignored, 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 energy that drives the flow of the siphon** is the difference in water level between the inlet and outlet of the siphon pipe, because the potential energy of the inlet of the pipe is greater than the potential energy of the outlet, and the hydrostatic pressure of the inlet and outlet is equal (equal to atmospheric pressure), thus prompting 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.

The conditions to be met for the siphon to succeed are, 1The material to be siphoned must be a liquid that can flow. 2.There should be a height difference in the liquid level. 3.From the high liquid level to the low liquid level.

1.The tube is filled with liquid first, so that the gravity of the water column between the highest point of the straw and the high liquid level is less than the gravity of the water column between the highest point and the low liquid level, which is necessary.

2.The height of the highest point of the pipe from the higher liquid level shall not be higher than the height of the water column supported by atmospheric pressure, and one atmospheric pressure shall support the water column at a height of meters.

3.The end face of the outlet must be below the high level. In this way, the downward pressure (atmospheric pressure and water pressure) on the liquid level at the outlet end is greater than the upward atmospheric pressure, ensuring the outflow of water.

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.

Siphon is a hydrodynamic phenomenon that can be used to pump liquids without the aid 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.

In May 2010, Dr Stephen Hughes of the Queensland University of Technology in Australia said: "The liquid in the siphon is caused by gravity to flow from the top to the bottom, and the water from the shorter top end is drawn up and then to the bottom by the longer and downward-facing end." ”

This phenomenon is caused by the gravitational force and potential energy difference between liquid molecules, and this strange phenomenon was discovered as early as the 1st century BC.

Basic principle. 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. Due to the different pressures at the nozzle, the water will flow from the high-pressure side to the low-pressure side until the pressure at the nozzle is equal, and the water surface in the container becomes the same height, and the water stops flowing. The siphon phenomenon is used to quickly pump out the water in the container.

Of course, gravity also plays an important role in the siphoning process.

Hope it helps!
