Hydraulics & Fluid Mechanics True one-dimensional flow occurs when 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 magnitude and direction of the velocity do not change from point to point in the fluid the direction and magnitude of the veiocity at all points are identical 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 magnitude and direction of the velocity do not change from point to point in the fluid the direction and magnitude of the veiocity at all points are identical ANSWER DOWNLOAD EXAMIANS APP
