Hydraulics & Fluid Mechanics The shear stress distribution for a fluid flowing in between the parallel plates, both at rest, is zero at the mid plane and varies linearly with distance from mid plane zero at plates and increases linearly to midpoint parabolic distribution across the section constant over the cross section zero at the mid plane and varies linearly with distance from mid plane zero at plates and increases linearly to midpoint parabolic distribution across the section constant over the cross section ANSWER DOWNLOAD EXAMIANS APP
Hydraulics & Fluid Mechanics True one-dimensional flow occurs when 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 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 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 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 ANSWER DOWNLOAD EXAMIANS APP
