As air is moved through a duct by a fan, friction between the air molecules and the sides of the duct creates a resistance to movement. Friction loss charts are available to determine the friction loss for a given quantity of air passing through a given size of duct, per 100 feet of duct.
You know that a section of exhaust duct is 64 meters long, but you cannot determine the friction loss unless the duct length is in feet. You know that one meter is
equal to 3.28 feet. How long is the 64-meter section of duct in feet? Round your answer to a whole number,
