Explain characteristics of streamlines.

Explanation

Characteristics of streamlines :
(i) In a steady flow streamline can never intersect each other .
(ii) The tangent drawn at point on the streamline indicates the direction of velocity of fluid particle at that point.
(iii) The velocity of each fluid particles passing at a point on streamline is same but it is different at different point.
(iv) Widely spaced streamlines indicates region of low speed and closely streamlines indicates region of high speed .
