Which of the following is correct?

1) Two streamlines can never intersect with each other and neither a stream line can intersect with itself.

2) distance between two streamlines is inversely proportional to the velocity of flow.

3) A streak line is the line formed by joining the location of a single fluid particle at different intervals of time.

4) A path line is the line formed by joining the location of different fluid particles originating from a fixed location at a given interval of time

5) For a steady path, streamline, streak line, and path line will coincide.
