Which of the following diagrams does not represent a streamline flow ?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
D
In a streamline flow at any given point, the velocity of each passing fluid particles remains constant. If we consider a cross-sectional area, then a point on the area cannot have different velocities at the same time, hence two streamlines of flow cannot cross each other.
