Fluid flow:

The state in fluid dynamics of a fluid in motion is determined by the type of fluid (e.g., newtonian, plastic, pseudoplastic, dilatant); the properties of the fluid such as viscosity and density; the geometry of the system; and the velocity.

Thus, under a given set of conditions and fluid properties, the fluid flow can be described as plug flow, laminar (called also newtonian, streamline, parallel, or viscous) flow, or turbulent flow.
