The viscosity of a fluid measured at a given shear rate at a fixed temperature. In order for a viscosity measurement to be meaningful, the shear rate must be stated or defined.

The ratio of shear stress to rate of shear of a non-Newtonian fluid such as lubricating grease, or a multi-grade oil, calculated from Poiseuille’s equation and measured in poises. The apparent viscosi [..]

Measure of the viscosity of a non-Newtonian fluid under specific temperature and shear rate conditions.

The viscosity determined in capillary viscometry without making a correction (Rabinowitsch) for shear thinning. The apparent viscosity is equal to the shear stress divided by the apparent shear rate, [..]

A measure of the viscosity of a non-Newtonian fluid under specified temperature & shear. Viscosity is expressed in units of centipoise (cP).

<physiology> This refers to the ratio of shear stress to shear rate in a fluid, this ratio is dependent on the rate of shear. (09 Oct 1997)

1. The viscosity of a fluid measured at a given shear rate at a fixed temperature. In order for a viscosity measurement to be meaningful, the shear rate must be stated or defined. 2. The viscosity of [..]

the ratio of shear stress to rate of shear of a non-Newtonian fluid such as lubricating grease, calculated from Poiseuille’s equation and measured in poises. The apparent viscosity changes with changing rates of shear and temperature and must, therefore, be reported as the value at a given shear rate and temperature.
