the direction and magnitude of the veiocity at all points are identical

the velocity of successive fluid par-ticles, at any point, is the same at suc-cessive periods of time

the magnitude and direction of the velocity do not change from point to point in the fluid

the fluid particles move in plane or parallel planes and the streamline pat-terns are identical in each plane
