incompressible

Engineers describe these conditions as incompressible flow and compressible flow.

Another important result involved the Navier-Stokes equations, which describe the dynamics of incompressible fluids.

As the science fiction author Ted Chiang writes, "experience is algorithmically incompressible."

Most hydraulic tools utilize incompressible fluid, or fluid at maximum density, in order to create the necessary pressure for separating large portions of a vehicle.

In the early years of the 20th century, several British scientists advanced technical, mathematical accounts of lift that treated air as a perfect fluid, meaning that it was incompressible and had zero viscosity.
