What are compressibile and incompressible flows ?


A compressible flow is one in which the density is constant throughout the flow.  Liquids are generally assumed to be incompressible.  

A liquid flowing through a pipe is an example of compressible flow.

Incompressible flow is one in which the density of the fluid is not constant.

Example: The flow of gas through a pipe is an example of compressible flow.
