The following statements are true about steady flow streamlines except
A) streamlines trace out paths followed by a small volume of fluid.
B) the fluid velocity is the smallest where the streamlines are the densest.
C) streamlines never cross.
D) the fluid velocity is tangent to the streamlines at any given point.

Question

Streamlines are closest together where the fluid velocity is highest, not lowest. This is due to the principle of conservation of mass, which implies that as the cross-sectional area of flow decreases (streamlines come closer together), the velocity must increase to maintain a constant flow rate.
