Which of the following statements about fluid flow is false?
A)As the velocity of a stream increases,laminar flow may change to turbulent flow.
B)The viscosity of most fluids increases as temperature increases.
C)Most streams and rivers are turbulent.
D)The more viscous the fluid,the more likely the flow is laminar.

The viscosity of most fluids actually decreases as temperature increases, not increases. This is because the increased kinetic energy at higher temperatures allows the fluid molecules to move more freely relative to each other, reducing internal friction.
