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 aricf direction of the velocity do not change from point to point in the fluid

velocity, depth, pressure, etc. change from point to point in the fluid flow.

steady

unsteady

uniform

laminar

the flow is steady

the flow is streamline

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

size and cross section change uniform¬ly along length

steady uniform

non-steady non-uniform

non-steady uniform

steady non-uniform

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

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