Two dimensional flow occurs when

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

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

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

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