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...
