thanks sirji nice

Hi everyone, I am sorry, I still don't get the point what really happens if incompressible fluid flow through the CD nozzle? why the density change can affect the acceleration of the compressible fluid thanks

For an incompressible fluid, the sonic velocity will be infinite. So there will not be the same effect of acceleration of fluid in diverging section as observed in compressible fluids. It will always be subsonic and act like a venturi tube (accelerating in converging section and decelerating in diverging section). I am also trying to learn this topic, pardon me if I am wrong. This is only my opinion based on what I could gather so far. Please let me know if you do find the answer.
