Re: Air Flow in a bypass valve

Air is a fluid, no doubt, definition stated.  The issue here is not fluid
not fluid.  The issue here is compressible vs. not compressible.  
Gases are.
Liquids are not.
That's why you blow your A/C compressor if you put too much liquid
in the low side port.  

Air is subject to Charles' Law, Boyle's Law and approximations can be
using the Ideal Gas Law.  This means that Temperature, Pressure, and
Volume are related and affect each other.  When you change volume, you
seriously affect flow characteristics of the fluid.  Temperature also
the viscosity.
