viscosity

That viscosity limit depends on the Planck constant, a number at the heart of quantum mechanics, the math that governs physics on very small scales.

The lab has also developed various mixtures of magnetic particles and fluids that have “odd viscosity” — a sort of frictionless viscosity that enables waves to travel across the surface of the mixture without losing any energy.

He showed that the knots, links and writhing — ignoring the twisting — don’t lose their combined helicity to viscosity.

For half a century it’s been known that vortex helicity is conserved in an ideal fluid — basically, a fluid that has no viscosity, meaning it offers no resistance to an object pushing through it.

That means its viscosity — how thick it is — changes when force is applied to it.

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.
