Understanding Kinematic Viscosity
Kinematic viscosity (ν) is a measure of a fluid's internal resistance to flow under gravitational forces. It is defined as the ratio of the fluid's dynamic viscosity (μ) to its density (ρ).
Formula: Kinematic Viscosity (ν) = Dynamic Viscosity (μ) / Density (ρ)
The SI unit for kinematic viscosity is square meters per second (m²/s). The CGS unit Stokes (St) (cm²/s) and its submultiple Centistokes (cSt) (mm²/s) are also commonly used.
| Substance | Kinematic Viscosity (m²/s) | Kinematic Viscosity (cSt) |
|---|---|---|
| Water | 1.004 × 10-6 | 1.004 |
| Air | 1.516 × 10-5 | 15.16 |
| Olive Oil (approx. density 918 kg/m³) | 8.82 × 10-5 (0.081 Pa·s / 918 kg/m³) | 88.2 |
| Glycerine (approx. density 1261 kg/m³) | 1.12 × 10-3 (1.412 Pa·s / 1261 kg/m³) | 1120 |
