= Streamlines, streaklines, and pathlines
{wiki=Streamlines,_streaklines,_and_pathlines}
In fluid dynamics, streamlines, streaklines, and pathlines are three different ways to visualize the flow of a fluid, particularly in a flow field. Each of these concepts provides insight into the behavior of fluid particles in motion. \#\#\# 1. Streamlines: - **Definition**: A streamline is an imaginary line in a fluid flow field that is tangent to the velocity vector of the fluid at every point.
