Rain is water falling in drops from the clouds.
The rain is divided by its diameter.
Water droplets with a diameter of 0.1mm to less than 0.5mm are called drizzle, and those with a diameter of 0.5mm to 8mm are called raindrops.
The shape is different by its diameter.
0.5mm to less than 3mm is circular, 3mm or more is oval.
Did you think raindrops are teardrop-shaped?
For example, when the tap is not shut perfectly, the shape of the water drop is teardrop-shaped on the end of the faucet.
However, when the water leaves the faucet, it changes its shape to a spherical shape due to its surface tension.
So, there is no teardrop-shaped liquid in the middle of falling.
雨は雲から水滴となって落ちてくるものです。
雨は直径によって分けられます。
直径0.1mm以上0.5mm未満の水滴は霧雨、直径0.5mm以上8mmのものは雨粒と呼ばれます。
形は直径によって異なります。
直径0.5mm以上3mm未満のものは円形、3mm以上のものは楕円形です。
雨粒は涙型だと思っていましたか?
例えば、蛇口が完全に閉まっていないと、蛇口の先で水滴は涙滴型になります。
しかし、水が蛇口から出ると、表面張力によって球形に変化します。
そのため、水滴が落ちる途中で涙滴型になることはありません。
