Question

Which of the following is the dimension of kinematic viscosity?

(a) [L^1 T^-1].

(b) [L^1 T^-2].

(c) [L^2 T^-1].

(d) [L^2 T^-2].

This question was posed to me in an interview.

My query is from Viscosity in division Properties of Fluids of Fluid Mechanics

Answer 1

The correct choice is (c) [L^2 T^-1].

To elaborate: ν = μ/ρ, where ν = kinematic viscosity, μ = dynamic viscosity and ρ = density of the fluid.
