Area velocity relationship for compressible flow

$\therefore A\times V=\text{constant}$

Above equation proof that as the area increases, velocity decreases.

But incase of compressible fluid, the continuity equation is given by

$\rho AV=\text{constant}..............(1)$

From this it is clear that with change in area, both velocity and density are affected.

$\therefore \rho …
