Hydraulics & Fluid Mechanics
Steady flow occurs when

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
the fluid particles move in plane or parallel planes and the streamline pat-terns are identical in each plane
the direction and magnitude of the velocity at all points are identical
