Steady flow occurs when

A the direction and magnitude of the velocity at all points are identical
B the velocity of successive fluid par-ticles, at any point, is the same at suc-cessive periods of time
C the magnitude and direction of the velocity do not change from point to point in the fluid
D the fluid particles move in plane or parallel planes and the streamline pat-terns are identical in each plane

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