Dynamic Viscosity
Dynamic (absolute) viscosity is the tangential force per unit area required to move one horizontal plane with respect to the other at unit velocity when maintained a unit distance apart by the fluid.

Kinematic Viscosity
Kinematic viscosity is the ratio of absolute or dynamic viscosity to density -- a quantity in which no force is involved. Kinematic viscosity can be obtained by dividing the absolute viscosity of a fluid with its mass density.
| Temperature - T - (°F) | Kinematic Viscosity - ν - (ft2/s) x 10-5 |
|---|---|
| 32 | 1.924 |
| 40 | 1.664 |
