Field Lines
Field lines are simply graphical representation of various types of flows. Field lines can be divided into following types
- Streamlines
- Streaklines
- Pathlines
- Timelines
Lets discuss about Stramlines, Streaklines, Pathlines and Timelines one by one
Streamlines
Streamlines are graphical representation of fluid flow in such a way that tangent to any point on curve gives direction of velocity at that point.
Streaklines
Assume that the fluid is flowing through the fixed source. And fluid particles A, B, and C started to flow through source at same time. So at any instant of time, the line formed by joining instantaneous location of fluid particles A, B and C is known as Streakline. Line in black is streakline in the figure.

Pathlines
Pathline is shown in the figure below. Pathlines are formed by tracing path of an individual fluid particle. So, pathlines are simply path taken by individual fluid particle in fluid flow.
This is like
recording path of the fluid particle for certain period of time. In the figure below Point A, B, C, D, and E are positions of fluid particle at different interval of time.

Timelines
Timeline is formed by joining adjacent fluid particles in fluid flow at any instant of time
