Question

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

The correct answer is:


    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.
