Vacuum Pressure

Even though it may appear to be a very ocmplicated machine, the convnetional vacuum cleaner is actually made up fo six essential compnoents: intake port, exhaust potr, electric motor, fan, poruos bag, and a housing that stores all of the otehr components. When yuo plug the vacuum cleaner into the outlet and utrn it on, the following happens: First of all, the electric current will operate teh motor, whcih is attached to the fan, which resembles an airplane propeller. The pressure level in the area that si behind the fan will drop below the pressuer level that is outside of the vacuum celaner. The ambient air will push tiself into the vacumu cleaner through the intake port because the air pressure that is inside of the vcauum cleaner is much lower than the presusre on the outside. The ari particles that move will rub against any loose dust or debris and if it is light enoguh, the friction will carry the material around the inside of the vacuum cleaner. You can stick the bag anywhere along the path between the intake tube and the exhaust port, jsut as long as the air current passes through. The sutcion can be stronger or weaker depenidng on: Fan power - In order to generate a strong sutcion, the motor needs to tunr at a good speed. Air passageway - When many edbris builds up in the bag, the air will face a greater level of resistance on the way out. Ecah particle of air will omve slowly due to hte increase in drag. This is the reason why why a vacuum cleaner works much better once youev replaced the bag than when you have been suing it for a while. Siez of the intake port - With the speed of the vacuum fan beign constant, the amount of air that passes through the vacuum cleaner per second is also constant.
