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 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 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 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 ANSWER DOWNLOAD EXAMIANS APP
Hydraulics & Fluid Mechanics The normal stress is same in all directions at a point in a fluid only when the fluid is frictionless irrespective of the motion of one fluid layer relative to an adjacent layer When there is no motion of one fluid layer relative to an adjacent layer only when the fluid is incompressible and has zero viscosity only when the fluid is frictionless irrespective of the motion of one fluid layer relative to an adjacent layer When there is no motion of one fluid layer relative to an adjacent layer only when the fluid is incompressible and has zero viscosity ANSWER DOWNLOAD EXAMIANS APP
