Airflow, or air flow, is the movement of air. The primary cause of airflow is the existence of air. Air behaves in a fluid manner, meaning particles naturally flow from areas of higher pressure to those where the pressure is lower. Atmospheric air pressure is directly related to altitude, temperature, and composition.In engineering, Airflow or air flow is a measurement of the amount of air per unit of time that flows through a particular device.
The flow of air can be induced through mechanical means (such as by operating an electric or manual fan) or can take place passively, as a function of pressure differentials present in the environment.
I have wondered for a long time can we add or remove electrons to air molecules. Create charged fields to force them to move over a surface at high speed. I am thinking only the air in contact with the surface or a % to control the air in contact with the surface. I picture a surface covered by...
Can anyone suggest a site where I can get a crash course in air flow? What I am looking for is pressure drop verses various volumes, speed, duct size, shape, etc. I have spent over an hour searching the net, but haven't had any luck. Thanks.
Hello all,
Here's my problem, verbatim:
An aircraft wing requires a lift of 25.4 lb/ft^2. If the speed of flow of the air along the bottom surface of the wing is to be 500ft/s, what must be the speed of flow over the top surface of the wing to give the required lift?
(NOTE: Density of air...
