Bernoulli's principle is that in the same fluid quality, the flow velocity is large and the du pressure is small; the flow velocity is small and the pressure is strong. The fluid will automatically flow from high pressure to low pressure. When passing through the trigeminal tube, the low-speed flowing water flows to the high-speed flowing air. The water is torn into small drops by high-speed air (Imagine that the water flowing out of the faucet is slow at first, it is a column of water; but then the speed gradually increases and becomes one drop after another). These small drops of water became mist after spraying out.
2. The principle of high-speed water flow breaking into small water droplets after encountering obstacles:
It uses the principle of pressing water into a thin tube to cause high-speed water flow. When the high-speed water flow encounters an obstacle, it splits into small water droplets. The situation is like plugging the faucet with your fingers. Household sprayers often use this structure, and the cost is low.
