airflows, plural;
  1. The flow of air, esp. that encountered by a moving aircraft or vehicle

  1. the flow of air; "she adjusted the fan so that the airflow was directed right at her"
  2. any flow of air, especially the motion of air around a moving aircraft or aerofoil
  3. The distribution or movement of air.
  4. The motion of air relative to the surface of a body moving through the air. A streamlined vehicle design creates a smooth airstream as the vehicle moves, reducing drag and increasing fuel efficiency.
  5. One of several ways of evaluating vacuum efficiency. see "vacuum pressure"
  6. the movement of air over and under a surface, such as a wing
  7. When a central vacuum cleaner is started, it creates a vacuum or an area of low pressure. Outside air rushes in to fill this vacuum. This rush of air or "Airflow" is controlled and directed for maximum cleaning efficiency.
  8. The amount of air sent to the vocal cords; the correct amount of air needed to coordinate with the proper vocal cord tension. Excessive airflow is called “air blast”.
  9. The flow of air or gas that goes over the outside finned surface of the coil. The direction of the airflow in relationship to the supply and return headers is important on certain coil types (see Right and Left Hand).
  10. Measures the amount of air that moves though a vacuum cleaner and is usually expressed in CFMs or Cubic Feet per Minute. This is one of the most important criteria for determining a vacuum cleaner's performance. Generally speaking, the better the airflow; the more efficient the vacuum.
  11. Beginning the process of speaking by releasing an exaggerated amount of air (exhalation) just prior to gently adducting the vocal folds to initiate phonation. (Reduces laryngeal blocks)
  12. Managed airflow enables a painter to get maximum efficiency of the paint sprayed while directing overspray away from the painted finish. ...
  13. Cubic Feet/Minute. The Cfm needed from a heater can be found with the following formula: Cfm = (Btu / Hr (out))/ Air Temp Rise x 1.08
  14. Luftfluss, Luftströmung
  15. 172 lb/s (78.0 kg/s)
