Im trying to find a similar expression for the bernoulli equation but for a compressible flow at a nozzle exit. Does a simple solution exist?

(I know.. ten years later but... ).
The density can no longer be assumed constant throughout the flowfield in compressible flow computations. This should violate the derivation assumptions for Bernoulli's equation. However, as shown in this link, see Sec. 3.8, Bernoulli's equation can be modified for compressible flows.

Well I had been watching the Bugs Bunny show at the time of the question!
I have recently been reading each post starting from the oldest one in the forum. Many interesting entries, so many! Highly recommended till the quarantine ends .
