n. pl. vis·cos·i·ties
1. The condition or property of being viscous.
2. Physics Coefficient of viscosity.

viscosity

(vɪsˈkɒsɪtɪ)
n, pl -ties
1. the state or property of being viscous
2. (General Physics) physics
a. the extent to which a fluid resists a tendency to flow
b. Also called: absolute viscosity a measure of this resistance, equal to the tangential stress on a liquid undergoing streamline flow divided by its velocity gradient. It is measured in newton seconds per metre squared. Symbol: η See also kinematic viscosity, specific viscosity

(vɪˈskɒs ɪ ti)

n., pl. -ties.
1. the state or quality of being viscous.
2.
a. the property of a fluid that resists the force tending to cause the fluid to flow.
b. the measure of the extent to which a fluid possesses this property.

vis·cos·i·ty

(vĭ-skŏs′ĭ-tē)
The resistance of a substance to flow. A substance that can flow easily has a low viscosity. A substance that cannot flow easily has a high viscosity.

Drug developers and device designers are increasingly working in collaboration to address the goal of patient self-administration for self injecting high viscosity drugs.
Charles Kim, CEO and founder of Viscosity North America, said, “Viscosity's managed services business and public cloud portfolio and service offerings have exploded, fueling the need for additional space as well as personnel and resources.
The aim of this paper is to report from experimental results of viscosity, the effect of temperature on the kinematic viscosity of three oils.
In any event, this relationship clearly shows that relatively modest changes in molecular weight (MW) result in large changes in melt viscosity when this viscosity is measured at a very low shear rate.
Blood viscosity is a measurement of the thickness and stickiness of an individual's blood and is associated with all major risk factors for cardiovascular disease as well as being implicated in cognitive dysfunction, complications of diabetes, preeclampsia, intrauterine growth retardation, migraines, and other conditions.
Application -- whether it is brushing, reverse roll coating, or spraying -- is a high stress process, so a high shear stress also must be applied during viscosity measurements.
Typically, the suspension, when subjected to a shearing flow, may exhibit a yield stress or an extremely high viscosity at low shear rates, followed by shear thinning and even shear thickening at higher shear rates, and time-or strain-dependent behavior as well.
The company says that the rotational viscometers are used for quick and reliable tests and comparative viscosity measurements according to recognized standards in quality control.
Intrinsic viscosity is widely used to quantify molecular weight and forms part of the specification for many bulk polymers, including polyethylene terephthalate (PET), polyvinyl chloride (PVC) and nylon.
Numerous correlations have been proposed to calculate the oil viscosity.
Some of the attributes that secondary surfactants impart to a formula include increased viscosity, stabilized foam and reduced skin and eye irritation.
Viscosity (resistance to flow) is related to specific gravity (density), although the relationship between the two is not direct, as the table below shows.
