Hydraulics & Fluid Mechanics Uniform flow occurs when size and shape of the cross section in a particular length remain constant size and cross section change uniformly along length the flow is streamline the flow is steady size and shape of the cross section in a particular length remain constant size and cross section change uniformly along length the flow is streamline the flow is steady ANSWER DOWNLOAD EXAMIANS APP
Hydraulics & Fluid Mechanics Steady 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 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 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 velocity at all points are identical ANSWER DOWNLOAD EXAMIANS APP
