Principle of agricultural sprayer

One uses the Bernoulli principle. Bernoulli's principle says that in the same fluid, the velocity is high, the pressure is low, and the velocity is low, and the pressure is high. The fluid will flow automatically from high to low pressure. Through the Trident (the specific picture can not be drawn, their own understanding) , the low-speed flow of water flow to the high-speed flow of air. Water is pulled apart by high-speed air in small drops (imagine the water from the Faucet, at first slow, is the water column; but then gradually increasing the speed into a drop by drop) . These little drops of water squirt out and become fog. The second is to force water into a thin tube to create a high-speed flow, which breaks into droplets when it hits an obstacle. It's like rolling a faucet and having Ōsaki plug it with her finger. The domestic sprayer uses this kind of structure, the cost is low.
