How Does A Fan Work?
The Fan is an electronic device
that everybody use it in their
house. People use the fan to make
the air in the room cooler, especially in hot
day. However ,do you know how a fan works?
An electric fan has an electric
motor with some fan
blades attached to its rotating shaft. As the motor
spins, the fan blades rotate. Each blade is
angled a bit, and as the inclined plane of the blade
moves through the air, it forces the air ahead
of it forward. Each blade does this on a continuous
basis, and the result is a moving air stream.
The fan is taking air from the area behind
itself and blowing it out the front.
The fan generates a movement of
air, causing the warm dense
air to descend, and the cool dense
air to rise, thus creating a feeling of coolness
in the air.
