A streamline is defined as the path that a tiny element of fluid would take as the fluid flows. This is true for both laminar and turbulent flow. Moreover, streamlines are useful for visualizing and understanding fluid flow patterns. It is also important to note that streamlines can cross in both laminar and turbulent flow. Additionally, the velocity vector of a fluid element can be parallel, perpendicular, or at any angle to the streamline.
