Hydraulics & Fluid Mechanics Fluid is a substance that has the same shear stress.at a point regardless of its motion cannot remain at rest under action of any shear force cannot be subjected to shear forces always expands until it fills any container has the same shear stress.at a point regardless of its motion cannot remain at rest under action of any shear force cannot be subjected to shear forces always expands until it fills any container ANSWER DOWNLOAD EXAMIANS APP
Hydraulics & Fluid Mechanics Non uniform flow occurs when 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 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 ANSWER DOWNLOAD EXAMIANS APP
