Vacuum Cleaners



So this weekend I had to clean my room. My room has a carpet floor, which means that I had to use a vacuum cleaner. Your vacuum cleaner consists of an intake, a motor, a bag, and an exhaust. A fan powered by a motor rotates causing a change in pressure. the angled fan blades push air through the bag and out the exhaust. this flow of air is creating a change in pressure. there is more pressure in the back of the fan than in the front, which creates a suction. the suction is what picks up dust on the floor and pushes it into the bag. there is a constant flow of air through the vacuum created by the rotating fan. this enables dust and debris to get caught in the stream and eventually fall into the bag where it can be discarded later.
