Dimension of flow:-
A fluid flow is said to be one, two or three dimensional depending upon the number of independent space coordinates.
Steady flow:-
A flow is considered steady when the dependent fluid variables at any point do not change with time.
Unsteady flow:-
When the fluid is regarded as unsteady if the dependent variable change with time at a position in the flow. The example for unsteady flow is flow at varying rates through a duct.
