Mach Number > 0.3
Compressible Flow
As pressure changes along the flow, the change in fluid density is significant.

Definition: Ratio of Fluid velocity to speed of sound 
-
At higher altitude, temperature decreases. Hence, speed of sound is lower at higher altitude.
Mach Number < 0.3
Fluid is Incompressible
As pressure changes along the flow, there is no significant change in fluid density.
