Which of the following statement about viscosity is not true? it
A
depends on areas of the surfaces in contact
B
occurs in fluids
C
is independent of the relative velocity of the layers
D
depends on the tangential force between the layers
Verified Correct Answer: C.
Physical Principles & Numerical Solution
Is independent of the relative velocity of the layers is not true because:
Viscosity is dependent on the relative velocity of the layers in a fluid; it describes how the fluid flows when layers move relative to each other.
Viscosity depends on the area of the surface in contact
Viscosity is independent of normal reaction
Viscosity depends on the relative velocity between layers
