Question

Which of the following diagrams $\left(Figure\right)$ does not represent a streamline flow?

Answer 1

A streamline can be straight or curved and tangent at which gives the direction of the velocity. Two streamlines cannot cross each other because that would indicate two velocities at the point of intersection, which is impossible, so $\left(d\right)$ does not represent a streamline flow.


Final Answer:$d$
