Handmade air capture hood dimensions and openings
  1. Make a four-sided cardboard air hood with two open ends:
    • Large end: 61 cm x 61 cm (2 ft x 2 ft) (standard floor tile size)
    • Small end: 30.5 cm x 30.5 cm (1 ft x 1 ft)
  2. Place the hood with the large open end over a vented floor tile. Minimize air flow leakage by sealing seams on the hood, and by pressing the hood firmly against the floor.
  3. Hold the air flow meter at the small open end of the hood, in the center, to get a reading of the air velocity.
  4. Convert the air velocity reading to the air flow rate.

    The measurement in cubic feet per minute is:

    flow rate (ft 3/min) = flow velocity (ft/min) x area (1 sq. ft on small open end of hood)
