TYPES OF FLOW LINES
Whenever a fluid in motion, its innumerable particles move along certain lines depending upon the condition of flow.
1.PATH LINE
A path line followed by a fluid particle in motion. A path line shows the direction of particular particle as it moves ahead.
2. STREAM LINE
A stream line may be defines as an imaginary line within the flow so that the tangent at any point on it indicates the velocity at that point.
3.STREAM TUBE
A stream table is fluid mass bounded by a group of streamlines. The contents of a stream which are known as "Current Filament".
4.STREAK LINE
The streak line is a curve which gives an instantaneous picture of the location of the fluid particles, which have passed through a given point.
