Great question! While I cover these equations multiple times across the fliuds/aero lectures, I do not do an explicit derivation of the new compressible terms in the same way I do the incompressible ones. I tend to gravitate to connecting physical intuition to terms instead of perfect derivations, unfortunately. You might find the NASA resources helpful: www.grc.nasa.gov/www/k-12/airplane/nseqs.html. Hope this helps!
hi sir. I want to ask a question. if there are two conditions of compressible fluid flow in the same flow area but at a different speeds. why the higher velocity flow has a lower static pressure?. is it the same as the incompressible flow caused by the dynamic pressure? thanks
Hi! While I am certainly no compressible flow expert, I think you're on the right track of thinking. My interpretation is that it velocity and pressure still have the same trends in compressible flow as in incompressible flow, but compressible flow just means you need to account for other flow property changes, which is why you can't use Bernoulli's equation. Does this help?

Good Vid
Hey thanks!
Can you explain from where do you derive the "new" terms in min: 12:37 please?
