Hydraulics & Fluid Mechanics According to the principle of buoyancy a body totally or partially immersed in a fluid will be lifted up by a force equal to more than the weight of the body less than the weight of the body the weight of the body weight of the fluid displaced by the body more than the weight of the body less than the weight of the body the weight of the body weight of the fluid displaced by the body ANSWER DOWNLOAD EXAMIANS APP
Hydraulics & Fluid Mechanics The position of center of pressure on a plane surface immersed vertically in a static mass of fluid is at the centroid of the submerged area None of these always above the centroid of the area always below the centroid of the area at the centroid of the submerged area None of these always above the centroid of the area always below the centroid of the area ANSWER DOWNLOAD EXAMIANS APP

Hydraulics & Fluid Mechanics Non uniform flow occurs when 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 velocity at all points are identical velocity, depth, pressure, etc. change from point to point in the fluid flow 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 velocity at all points are identical velocity, depth, pressure, etc. change from point to point in the fluid flow 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 incompressible and has zero viscosity When there is no motion of one fluid layer relative to an adjacent layer irrespective of the motion of one fluid layer relative to an adjacent layer only when the fluid is frictionless only when the fluid is incompressible and has zero viscosity When there is no motion of one fluid layer relative to an adjacent layer irrespective of the motion of one fluid layer relative to an adjacent layer only when the fluid is frictionless ANSWER DOWNLOAD EXAMIANS APP
