I thought it was a coincidence, so I grabbed the plug and plugged the drain hole. After a while, I pulled it out again and found that it was still rotating counterclockwise. I kept staring at the end of the water, and suddenly thought of flushing the toilet, so I pressed the button of the water tank. Water? Wow? The ground gushed out. I was suddenly surprised to find that the water also rotates counterclockwise! I was dumbfounded and went to wash my face again. Naturally, when I discharged the water, I saw that the water was rotating counterclockwise. I confirmed a sentence in my mind: this is a rule, not a coincidence.
I can't figure out why the water can't go straight down. Why can't water rotate clockwise? Why is my heart full? Why? . So, I turned on the computer with a heart full of doubts. Originally, as early as the 1940s, Xie Piluo, a scientist at the Massachusetts Institute of Technology, discovered this phenomenon, and came to the conclusion that when an object is at a low latitude, its linear velocity from west to east is larger as the earth rotates. When an object moves from low latitude to high latitude, it will still maintain the linear velocity at low latitude. This inertia deflects the object eastward. In the northern hemisphere, the linear velocity of the water in the north of the bathtub is larger than that in the south, which will form a vortex, and the inertia to the east will make the water form a left spiral, which is counterclockwise. The southern hemisphere is just the opposite. Later, this phenomenon of water flowing counterclockwise or clockwise was called? Xie Piluo phenomenon? .
Oh, I see. It suddenly dawned on me.
