Air is a fluid AND it is a gas.  Air is NOT a liquid.  Common english
butchers these terms all the time.  I say again, air is a fluid.  So is
water and other liquids.  But air is NOT a liquid.

Again, I use the example: a square is a rectangle, but not all rectangles
are squares...

HTM.  BTW, you can't use fluid dynamics equations on things that are not fluids!
