I just learned that an incompressible fluid must have zero divergence within a given control volume. Given that the divergence of a fluid at a point(x,y,z) can be found by taking the scalar sum of the of the x, y, z acceleration vectors at the given point, wouldn't this mean that water flowing downstream, consequently accelerating, would have a nonzero divergence? Does that mean that accelerating water is compressible?
