Would one liter of water falling from high altitude knock you dead?
Everyone knows the people are hit by falling object from high altitude is very dangerous. But if the object is one liter of water, will it dangerous? The answer is “No”. The reason of this answer is even if a large volume of water polo in the process of falling from a height, it is subjected to the action of the air resistance, which makes it split into numerous small droplets. Droplets quickly arrival "terminal velocity" (gravity and resistance balance) because of the role of air resistance, then it will not accelerate.

Assuming diameter of water polo is d, the magnitude of gravity act on water polo and d^3 will be direct proportion, the magnitude of resistance act on water polo and d^2*d^2 will be direct proportion. At this the larger diameter of the water polo, the greater terminal velocity, but also more energy of the water polo. That seems people can be killed. The making the water polo remain in full force is the surface tension. Surface tension, usually represented by the symbol γ, at 20 degree Celsius the γ is 72.75 mN/m. The following analogy to rain, raindrop terminal velocity is about 8 ~ 9m / s, estimates the diameter of maintain complete raindrops form is about 4mm. Actually measuring the maximum diameter of raindrop not more than 5.5mm, diameter of more than 5.5mm of raindrops will be deformed fragmentation. Thus, if there is a large volume of water polo in the process of falling from a height, it will split into numerous small droplets when it drop on the ground. Angel Falls is a waterfall in Venezuela. It is the world's highest uninterrupted waterfall, with a height of 979 meters (3,212 ft) and a plunge of 807 meters (2,648 ft). Water at the bottom of fall, has been change into mists, it is on the loose by the wind blows. There is a photograph about Angel Falls in the last
