Hydraulics & Fluid Mechanics Non uniform flow occurs when velocity, depth, pressure, etc. change from point to point in the fluid flow the velocity of successive fluid par-ticles, at any point, is the same at suc-cessive periods of time 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 velocity, depth, pressure, etc. change from point to point in the fluid flow the velocity of successive fluid par-ticles, at any point, is the same at suc-cessive periods of time 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 ANSWER DOWNLOAD EXAMIANS APP
