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 the weight of the body less than the weight of the body more than the weight of the body weight of the fluid displaced by the body the weight of the body less than the weight of the body more than the weight of the body weight of the fluid displaced by the body ANSWER DOWNLOAD EXAMIANS APP
Hydraulics & Fluid Mechanics Two 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 velocity 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 velocity 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
