Exactly. And from an engineering standpoint (with all due respect to
Mirriam Webster et at.) that's the difference between pneumatics and
hydrolics. Whatever the media invloved, pneumatic devices operate through
the flow of *compressible* substances while hydrolics operate through the
flow of *incompressible* substances. These require very different design
theories as they behave very differently.
