A flow is considered steady if the fluid characteristics like velocity, pressure, density, etc., at a point do not change with time.
Unsteady flow is defined as that type of flow in which the fluid characteristics like velocity, pressure, density change with respect to time. Eg. Flow of water in river.
A flow is said to be laminar when the various fluid particles move in layers (or laminae) with one layer of fluid sliding smoothly over an adjacent layer.
In a turbulent flow, the fluid particles move in an entirely haphazard or disorderly manner, that results in a rapid and continuous mixing of the fluid.
Compressible fluid is one in which the density changes from point to point.
Incompressible fluid is one in which the density is constant for the fluid flow.
When the velocity profile shape no longer changes with increasing distance, the flow is said to be fully developed.
