centriod of the displaced volume of fluid

center of the volume of floating body

centroid of the volume of fluid vertically above the body

center of gravity of any submerged body

the velocity of successive fluid par-ticles, at any point, is the same at suc-cessive periods of time

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 direction and magnitude of the velocity at all points are identical
