Hydraulics & Fluid Mechanics Steady flow occurs when 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 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 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 ANSWER DOWNLOAD EXAMIANS APP
