So do everyone know what a siphon is? In fact, the siphon is a hydrodynamic phenomenon that can pump liquid without the aid of a pump. After the liquid in the upper position is filled with an inverted U-shaped tubular structure (called a siphon tube), it opens to a lower position. Under this kind of structure, the liquid pressure difference between the two ends of the pipe can push the liquid over the highest point and discharge to the other end, mainly by the gravitational force acting on the siphon pipe. So when did this magical siphon appear? What is siphoning ?

The siphon was an ancient invention of mankind. As early as the 1st century BC, a strange siphon was created. The Chinese knew how to apply the siphon principle very early. The siphon tube manufactured by applying the siphon principle was called "Note", "Partial", "Thirsty Ukraine" or "Over Mountain Dragon" in ancient China. In the last years of the Eastern Han Dynasty there was thirst for irrigation. The ethnic minorities in the southwest region used a long curved bamboo tube to drink alcohol, which was also a physical phenomenon that applied siphon. In the Song Dynasty Zeng Gongliang's "General Wu Jing", a bamboo siphon tube was used to record the spring water blocked by the steep mountains. In ancient China, the siphon principle was also used to make a scorpion cone. Slug is an essential fire extinguisher in the war. In Song Dynasty Su Shi's "Dongpo Zhilin," Volume IV, it was recorded that Sichuan salt wells used saline water to suck salt water into the ground. The book contains: Take the bamboo as a cylinder, "the bottom is no matter what, it is a few inches over the skin, out of the water, breath from the air and open and close, a bucket of water to fight.
[Siphon principle analysis]
We can explain it with secondary school physics knowledge. This is a special application of atmospheric pressure and connected principle. We know that the corresponding liquid level of the two vessels is not the same, and we can use both pipes to communicate. Regardless of the shape of these tubes, there is always a tendency to keep the liquid level flat under the influence of the liquid's own gravity and atmospheric pressure. The specific explanation is that the flowing liquid is subjected to the interaction of forces and the liquid flows from a high place to a low place under such a force.
What are the siphon?
The essence of siphon is actually generated by the interaction of gravity and intermolecular cohesion. The liquid in the highest point in the tube attached to this device moves under the influence of gravity to the corresponding lower nozzle, which will generate a negative pressure inside the U-tube. This will cause the relevant liquid in the high position of the nozzle to be sucked into the highest point. In this case, we find that the liquid continuously flows into the low position container through the pipeline.
Since the corresponding air pressures on both sides are basically the same, the corresponding high position nozzle is at a relatively low position far from the depth of the liquid surface, that is to say it is deeper than the liquid level of the low position nozzle. Low, so we know that from the nozzle, the corresponding low pressure in the lower nozzle, but the liquid will still flow from the high container to the lower container. Therefore, we know the reason for this phenomenon is that the pressure here can only be transmitted to the liquid surface. Although the tube in the low cup has high pressure, it can't reach the high cup, so the liquid will flow down.
Xiao Bian concludes: The siphon effect was introduced for everyone. I hope to help everyone. For more relevant knowledge, please continue to pay attention to this website information platform. Follow-up will present more exciting content for everyone.
