How high can a drop of water fall to kill someone?

What are the chances of being killed by raindrops?

Anyone who can ask this kind of question must either have an extremely high IQ, or have an IQ that is in arrears. I once saw a joke. A guy joined a PhD group in order to increase his knowledge. Then someone asked a question: "Can a drop of water fall from a very high place and kill someone?"

< p>This person was confused and doubted whether he had joined the wrong group. However, this issue aroused heated discussion, and doctors with various titles and prestigious universities started a heated discussion. Listing formulas, calculating resistance, and various assumptions, we debated for a full hour. This guy finally couldn't stand it anymore and said, "Have you ever been exposed to the rain?"

After a brief silence, he was kicked out of the group.

Obviously, this joke tells us a truth: if we are not in the same circle, we cannot play together.

Can a drop of water kill someone? From how high can you crush someone to death? The answer is obvious, it can't be killed no matter what. However, if your imagination is big enough and you turn a little, you can imagine that raindrops can change. When it turns into a solid form - hail, it is hard to say whether it can kill people.

The power of water droplets depends entirely on the "environment" or "form".

Falling in the form of raindrops

In the process of falling, the raindrops will soon reach the so-called "terminal velocity" due to air resistance - the balance between gravity and resistance, and will no longer accelerate. Therefore, raindrops are not lethal. Its falling speed is maintained at an average of 10 meters/second, which is equivalent to someone riding a bicycle rushing towards you. However, this "bicycle" is a drop of rain, so it is not very powerful.

When water droplets turn into hail

Readers who just thought they couldn’t kill people are a little panicked when they saw this. When water droplets hit you in a solid form, they may still not be able to kill you. , but if it hits you in the head, you will be stunned for at least a while.

Compared with raindrops, hailstones are harder and larger in size. Some exaggerated ones can reach 15cm, which is about the same as an apple. If you want to try everything, you can find someone who hates you. Let him hit you on the head with an apple, and you can close your eyes tightly and shout the slogan "For science!"

The falling speed of hailstones can theoretically reach 50 meters/second. It fell on his head, and he was knocked unconscious even if he wasn't hit to death.

A drop of water cannot hit anyone no matter how high it falls. However, when its shape changes, from a drop of water to a hailstone, it changes from Impossible to I'm possible ( It is possible).

What you consider to be common-sense questions will give you another explanation when it comes to scientists, so don’t jump to conclusions about anything. Next time someone asks you “Can raindrops kill people?”, it’s best to It's better to avoid it quickly. The reasons are as follows:

People who can ask such questions are either authorities, and you will definitely not be able to explain them; or they are crazy, and you will not be able to explain them clearly.

You just need to know in your heart whether water droplets can kill people. The complex scientific knowledge behind it is not of concern to ordinary readers. If you are interested, you can go online to find the answer.
