Airwatt

From Wikipedia, the free encyclopedia

An airwatt or air watt is a unit of power very close to the watt which is used for various vacuum cleaning systems, such as vacuum cleaners. The airwatt is derived from English units. ASTM International defines the airwatt as 0.117354 * F * S, where F is the rate of air flow in ft3/s and S is the pressure in inches of water. This makes one airwatt equal to 0.9983 watts. [1]
