Concept:

  • Viscosity: It is a property of a fluid to oppose relative motion between its layer.
    • The coefficient of viscosity is “η“ and dimension is [ ML-1T-1].
  • Kinetic Viscosity: It is a measure to the inherent resistance of the of a fluid to flow when no external force is acted expect gravity.
    • Kinetic Viscosity = coefficient of viscosity / fluid mass density
    • V = η / ρ

Explanation:

  • Dimensional formula of viscosity is [ ML-1T-1].
