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 direction and magnitude of the veiocity at all points are identical the magnitude and direction of the velocity do not change from point to point in the fluid the fluid particles move in plane or parallel planes and the streamline pat-terns are identical in each plane 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 veiocity at all points are identical the magnitude and direction of the velocity do not change from point to point in the fluid the fluid particles move in plane or parallel planes and the streamline pat-terns are identical in each plane 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 only when the fluid is incompressible and has zero viscosity When there is no motion of one fluid layer relative to an adjacent layer only when the fluid is frictionless irrespective of the motion of one fluid layer relative to an adjacent layer only when the fluid is incompressible and has zero viscosity When there is no motion of one fluid layer relative to an adjacent layer ANSWER DOWNLOAD EXAMIANS APP
