Why do rocket engines look the way they do? In this video, I'll be explaining what a converging-diverging (CD) nozzle is, and how the flow changes as it passes through it.
See the Relevant Videos section below for some more in-depth videos on each of the flow states, including examples!

===== NOTES =====
=================
► At 11:28, I say "so far, we have subsonic flow throughout the nozzle for all these cases." I meant to say that we have isentropic flow throughout the nozzle for all these cases.
