Why two streamlines cannot cross each other?

tangentto streamline at a point gives the velocity of fluid element at that point.
if two streamlines cross,then at the in tersection point ,there will be 2 tangents and hence two directions of velocity which is not possible.
the same reason exists for electric lines of force.

Exactly rishabh.

The two stream lines cannot intersect as it will imply the two directions of velocity of a point on the streamline which is impossible.

Its just analogous to the fact that two Electric lines of force can never intersect.

The Scientist does not study nature because it is useful; he studies it because he delights in it, & he delights in it because it is beautiful. If nature were not beautiful, it would not be worth knowing, life would not be worth living. Ofcourse I do not here speak of that beauty that strikes the senses, the beauty of qualities & appearances; not that I undervalue such beauty, far from it, but it has nothing to do with science; I mean that profounder beauty which comes from the harmoniuos order of the parts, & which a pure intelligence can grasp.
