Why does the dust accumulate on the wings despite moving around all the time?

 

Now every house uses fans and they are operated throughout the year except for specific months.

 

But why does the blade or wings of this machine that provides us with cold air gather dust, even though the fan should blow the dust away?

 

The answer is not simple but interesting.

 

But before that, know what is called dust.

 

What's around?

Most of the dust in our home consists of dead cells of human skin and hair.

 

Our body continuously removes thousands of cells every day while making skin cells, as a result of which a lot of microscopic particles of dust accumulate in the atmosphere.

 

These particles are circulating in our house all the time and apart from this, soil particles, paper fiber, textile fiber and other materials are also part of the dust.

 

So  why does dust gather in the wings?

In fact, this does not happen without reason, but there is a scientific reason behind it.

 

The reason for this is hidden in static electricity (electrical energy that does not flow in the form of electric current).

 

When the fan rotates resulting in the formation of air molecules around the blades of the fan which makes us feel cool.

 

When these molecules are activated, an electric current is formed, especially at the edges of the fan blades.

 

This electric current attracts the dust particles in the atmosphere of the room and it starts accumulating on the blades.

 

This accumulation of dust particles attracts more particles and over time the blades begin to look dirty.

 

You can also easily experience it just you'll need 2 wings.

 

Use one of these fans all the time while using the other occasionally or not at all.

 

You will observe that the fan that is being used more is more dusty than the other.

 

By the way, along with the electric current, the movement of the blades also plays a role in this regard.

 

When these blades rotate, the speed of air on the surface of the fan is zero or zero, that is, there is no air, due to which the dust particles start to accumulate on the surface and freeze there.

 

The faster the fan rotates, the higher the speed of accumulation around it.
