Rain may be dangerous!!!!-hearttouch0929

The rainiest is probably the most beautiful among the natural phenomena. One of the most beautiful feelings wet in the rain. Nearly all of us have seen rain from our windows and raindrops. But how many people have scared the speed of this rain?

Medium size clouds live on average up to 8 kilometers above the ground. When the rain drops fall due to the gravity of this height, at the time of reaching the Earth, its velocity is about 396 meters in seconds. The velocity of this velocity is very clear and, if you give an example, it will be clear. The speed of the ordinary rifle bullet starts from 180 meters in seconds, where the speed of the rain velocity is 396 meters in seconds! Raindrops were supposed to be overthrown at such a high speed (what would have happened then what I was saying), but in reality it is not. The main reason for not being so excited is the viscosity.

The amount of viscosity that is interrupted by any fluid (such as fluid or air) is measured, its measurement is the viscosity. As the friction prevents the relative speed of two solid substances, the viscosity prevents the relative speed of the two levels of the fluid and tries to disrupt the motion. Although the friction ball is not dependent, the value of the viscosity force depends on the area of ​​the flow layer itself. For this reason, the viscosity ball works more in the larger droplets. But due to the size of the scales, the weight of the droplets also increased. As a result, the net velocity of Rainfall increases.

Again Stox's formula about viscosity can be easily shown that the ball that is obstructing the object is proportional to its velocity. That is, if any fibrous conductive, such as through the wind, falls under the influence of rain drops of gravity, then due to the acceleration of gravity it will increase its velocity and simultaneously it will continue to increase the pressure, so that the net acceleration of the rainwater will decrease. Once the net acceleration will become empty and the drops will fall on the surface with constant velocity. This motion, however, is known in many books as anesthesia.

That is to say, how fast the raindrops will fall and the height of the clouds are not dependent. Rather depends on its size. Due to moderate rainfall (the rainfall is comfortable), the radius of most of the fallen waterpoints is between 2.5 to 1.25 millimeters. If there is no transverse wind, now it can be shown by using different concepts of intestine and viscosity, that a rain density of 5 mm radius will fall on the ground at about 30 m in seconds.

That is, it turns out that the rain does not fall in the speed of 396 m / s. Rather, it falls on a speed that creates astonishing rhythm in the speed of tin; The human mind awakens love. This is because of the moderate speed of rainfall, so all the teenagers, especially teenagers, are so fond of rain in the rain.

When Baridhara was spreading across the body during the wet season, I did not give the description of the wonderful shivering that was shaken by body. And if this was not the viscosity, the rains of the house might have easily eroded; The sound of the rain would have turned into sound pollution.

The lovers could not enjoy the pleasures of the rain in the rain by the hands of two couples. It can be said that if there is no viscosity, the raindrops did not originate, there would not have been hundreds of songs of love that were centered around the rain. So much so that the poet could not write any poetry about rain and love, but poet Sukant could have found a match in the rain of second world war and found himself in the poem of pain.

As far as the hailstorm is harmful and unwelcome to us, our very favorite rain will be as unnecessary and unwanted if there is no viscosity.
