size and cross section change uniformly along length

the flow is streamline

size and shape of the cross section in a particular length remain constant

the flow is steady

the direction and magnitude of the veiocity at all points are identical

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 fluid particles move in plane or parallel planes and the streamline pat-terns are identical in each plane

vertically upwards

at e.g. of body

at metacentre

at center of pressure

force of friction

force of adhesion

a cylinder

a sphere

an airfoil

a circular disc or plate held normal to flow

between e.g. and center of pressure

below the center of buoyancy

above the center of buoyancy
