HYDRAULICS & FLUID MECHANICS QUIZ

above the center of gravity.

below the center of buoyancy

between e.g. and center of pressure

above the center of buoyancy

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

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

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
