Chapter 8, Problem 19RQ

To determine

Definition of streamlines and the change in pressure in crowded streamlines.

Answer to Problem 19RQ

The pressure is lower in the region of crowded streamlines.

Explanation of Solution

In fluid mechanics, the streamline is referred to as the path of the imaginary fluid particles in the fluid flow and carried out along with the flow. The streamlines shows the direction in which a fluid constituent having no mass will move around at any point in time.

The pressure becomes lower or lesser in the regions of crowded or narrow packed streamlines because the streamlines flow with higher vertical velocity in the crowded region.

Conclusion:

Therefore, the pressure is less in the regions of crowded streamlines.
