Hydraulics & Fluid Mechanics Steady 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 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 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 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 ANSWER DOWNLOAD EXAMIANS APP
