Question

The dimensional formula for coefficient of kinematics viscosity is

Answer 1

Kinematic viscosity is defined as the ratio of ability to diffuse a disturbance in momentum to ability of sustaining the original momentum.

Mathematically,
Kinematic viscosity (ν) = Dynamic viscosity (μ) / Density (ρ).

Dimensional Formula of Dynamic viscosity = M¹L^-1T^-1
Dimensional Formula of Density = M¹L^-3T⁰

Putting these values in above equation we get,
Dimensional Formula of Kinematic viscosity = M⁰L²T^-1
SI unit of Kinematic viscosity is m²s^-1
