viscosity

The oil pressure will vary according to weather conditions and viscosity of oil used.

By the old gravity systems, the flow of oil depended largely upon its viscosity, or thickness.

A viscous precipitate forms which frequently loses its viscosity when heat is applied.

The effect on gelation is also illustrated by the change of viscosity of the sol with time.

Both the suddenness of their formation and the slowness with which they widen are demonstrative of the non-viscosity of the ice.
