The liquid at the highest point in the tube moves to the lower nozzle under the action of gravity, which generates negative pressure inside the U-shaped tube, so that the liquid at the upper nozzle is sucked into the highest point, forming a siphon phenomenon.

Because the air pressure on both sides is basically the same, the depth of the high-level nozzle entering the liquid level is much lower than that of the low-level nozzle, so the pressure at the low-level nozzle is greater than that at the high-level nozzle, but the liquid will still flow from the high-level container into the low-level container.

This phenomenon occurs because the pressure here can only be transferred to the upper surface of the liquid. Therefore, although the pipe pressure in the lower cup is high, it can't be transmitted to the higher cup, so it can't stop the liquid from falling.

Extended data:

The essence of siphon is caused by liquid pressure and atmospheric pressure. Because h 1

However, when calculating the altitude relative to the atmospheric pressure of the earth, the pressure difference between point B and point C can be ignored. Therefore, p1-rhogh1>; P2-ρgh2, then the pressure at the left end of A is greater than that at the right end of A, and water moves in one direction under the action of atmospheric pressure and liquid pressure.

Siphon financial theory holds that technical analysis can solve the problem that fundamental analysis fails because of using insider information to profit groups. For example, it is entirely possible for a country to take advantage of the manufacturing tension to influence commodity prices to make a profit from venture capital, which is completely possible in a modern society with highly developed financial information.

International economic integration has formed a large-scale market that can accommodate national wealth. If insider information is used for arbitrage, it is sometimes very difficult to judge the fundamentals, and technical analysis can solve this deficiency. Technical analysis is not omnipotent, but independent fundamental analysis without technical analysis obviously cannot avoid many unknown events.
