Property of fluid. fan inside vacuum causes air pressure in machine to become less than the pressure of the air outside the machine- the outside air pressure pushes the air and dirt into the vacuum cleaner- A filter removes the dirt and releases the air.
Manometers are used to measure pressure exerted by fluids. It works on the principle of Pascal's law. Pascal's law states; In a closed system containing fluid at rest,change in pressure is transferred undiminished through out the fluid. Manometer uses a column of liquid to measure pressure (generally relative to the atmospheric pressure).The instrument is attached to the system whose pressure is to measured. If the pressure is greater than atmospheric pressure,the height of the liquid column increases.
