Kinematic Viscosity vs Dynamic Viscosity (mu)
Viscosity Conversion
Dynamic viscosity measures the shear resistance of a fluid. Kinematic viscosity is the ratio of dynamic viscosity to density.
Formula
nu = mu / rho
where mu is dynamic viscosity (Pa-s), rho is density (kg/m^3), and nu is kinematic viscosity (m^2/s). Kinematic viscosity is what appears in the Reynolds number formula.
Example Calculation
Water at 20 deg C: mu = 0.001 Pa-s, rho = 998 kg/m^3.
- 01nu = 0.001 / 1000 = 1.0 x 10^-6 m^2/s
- 02In centistokes: 1.0 x 10^-6 x 10^6 = 1.0 cSt
