The coefficient of viscosity \( \eta \) of a fluid is defined as the ratio of:

  1. A
    Shearing stress to strain rate
  2. B
    Normal stress to volume strain
  3. C
    Shearing force to velocity
  4. D
    Pressure to velocity gradient
View Answer & Solution

Correct answer · Option A

Shearing stress to strain rate

Explanation

By definition, coefficient of viscosity \( \eta = \frac{\text{Shearing Stress}}{\text{Strain Rate}} \).
