How Does The
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. And how does the fan work?
An electric fan is 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.
