How do you calculate air suction power?
Similarly, how do you find the suction power of a vacuum?
The sealed suction of a vacuum cleaner is measured in inches of water lift. This rating is taken when the motor is totally sealed, and the term refers to how many inches the motor will vertically lift a 1" column of water.
Similarly, how can you tell how powerful a vacuum cleaner is?
Use air watts This measuring method is usually about a number of watts a machine uses to carry a unit of air through a vacuum cleaner nozzle. It is the best measurement that shows the strength of suction. It works well with users who know cubic feet per minute and water lift of a vacuum cleaner.
Suction Pressure (Water Lift or Sealed Suction) Typical domestic vacuum cleaners can create a suction of 20 kPa. Pascal is a measure of pressure that equals to a pressure of 1 newton of force per square meter of area. 20 kPa would be 20000 N/m2 or around 2 tons per square meter, or around 200 cm (80 inches) of water.
