A 'Bingham plastic' is a viscoplastic material that behaves as a rigid body at low stresses but flows as a viscosity fluid at high stress.

This system is useful for low viscosity fluids, inks, paints, adhesives, and biological fluids.

Air drilling requires a faster up hole volume as the cuttings will fall faster down the annulus when the compressors are taken off the hole compared to having a higher viscosity fluid in the hole.

Reynolds number will be low for small objects, low velocities, and high viscosity fluids.

Swelling by contact with a low viscosity fluid causes an increase in dimensions, and also lowers the tensile strength of the rubber.

Because of its high temperature, modeling work has shown that the outer core is a low viscosity fluid (about ten times the viscosity of liquid metals at the surface) that convects turbulently.

Total losses can be regained through conventional use of increased viscosity and additives, or through use of unconventional methods such as pumping of golf balls, tree branches, rags, additive sacks, and other items in conjunction with, or followed by, a high viscosity fluid.

When heated to 49 C it liquefies to a high viscosity fluid that solidifies within minutes when exposed to room temperature.

As a fluid coupling operates kinetically, low viscosity fluids are preferred.
