Note: The dynamic viscosity (
η
) of a Newtonian fluid is given by:
η τ
= ×
dv dr /
where
τ
= shearing stress between two planes parallel with the direction of flow
dv dr /
= velocity gradient at right angles to the direction of flow.
The dimensions of dynamic viscosity are M L
-1
T
-1
and the SI unit is Pascal seconds
(Pa s).
The kinematic viscosity (
ν
) is the ratio of the dynamic viscosity to the density
ρ
The dimensions of kinematic viscosity are L
2
T
-1
and the SI unit is square metres per second
(m
2
/s).
