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