Chapter 1. Fluid Dynamics

20   ✅Section 1.1140 nanoseconds should become 140 picoseconds.

37   ✅Section 1.8In this section it is shown that the incompressibility condition (1.48) holds under many circumstances, when the typical length and time scales of the flow are such that their ratio is much smaller than the speed of sound. There can be exceptions though. Consider e.g. flow of a compressible gas through a channel with a thick porous medium. The large pressure difference across the channel will result in a large density gradient along the channel, so mass conservation implies that there will then also be a velocity gradient along the channel. This effect can be important in microfluidics.
