Sorry, but air is indeed considered a fluid in fluid dynamics. The flow
patterns of any fluid obeys the same general principles, whether it be
air, water, oil, etc.
You may very well argue that hydraulics implies not just a fluid but a
liquid, but you can't argue that air isn't a fluid.
----- End of forwarded message from John A. Tamplin -----
A liquid is an incompressible fluid.
A gas is a compressible fluid.
