How can we measure the viscosity of very viscous polymeric materials?

You need a viscosimeter made for the fluid you are measuring, but all viscosity measurements are done in the same way: you put a measured quantity of a fluid in a container with a known-size hole in the bottom, and time how long it takes for all the fluid to empty through the hole.

How does temorature affect viscosity?
Yes. Higher Temperature= Low viscosity Lower Temperature=High viscosity
What does centrepoise relate to?
Centrepoise is a measurement of viscosity. The higher the number, the more viscous (thick) the liquid is. At "room temperature", water has a nominal viscosity of 1.0
When a liquid has a high viscosity what does that mean?
A liquid with high viscosity is thick and runs slowly. Some example of highly viscous liquids are molasses, honey, and syrup.
What does viscosity measure?
Viscosity is the measure of the shear stress vs the shear strain of the fluid (in one tensorial direction). It is a derived property of fluids and cannot be directly linked to fluid parameters. There are typically two ways to measure fluid viscosity, test it in simple shear flow, and test it in elongation. Both tests will yield a fluids viscosity, although the results may be different. Definition- the state of being thick, sticky, and semifluid in consistency, due to internal friction. Let it be noted that 'viscosity' is only a term applied to newtonian fluids, because in fact some fluids do not have constant viscosity. This becomes very apparent when attempting to use the Navier Stokes equations on non-newtonian fluids. The 'viscous' closure term falls apart for these fluids. This is once again due to the fact that when you measure the 'viscosity' of a fluid, you are only measure one direction in the stress tensor, which for these fluids is not equal for all directions (seen in cases such as die swell). *See rheology for more information about this topic
Is water an ideal fluid?
Ideal Fluid:An incompressible fluid that has no internal viscosity.
Is Ostwalds viscometer used to measure viscosity of more viscous oil?
Yes, the Ostwalds viscometer can be used to measure the viscosity of more viscous oil.
Viscosity is the measure of how well liquids?
Viscosity is the measure of a fluids resistance to flow. The higher the viscosity the more viscous (the more resistance it has to flow); honey is generally much more viscous than water.
How do you measure the viscosity of a liquid?
you can measure it by dropping a lead ball into the liquid while timing it with a stop watch if it is runny then it is more viscous and when it is thick and not runny it is less viscous.
What is meant by a viscous liquid?
Viscosity is a measure of the thickness or how runny a liquid is. More viscous means thicker and syrup-like. Less viscous means more runny and more like water.
What is an example of high and low viscous material?
Viscosity is a measurement of how much a liquid resists flow or deformation -- viscous liquids tend to move more slowly than non-viscous liquids. An example of a highly viscous liquid might be honey or molasses; vinegar and water have low viscosity.
What does oil viscosity refer to?
The viscosity of a liquid is a measure of of "thick" the liquid is. E.g. Honey is very viscous, while water is not. In terms of motor oil, more viscous oil will thin out less at very high temperatures. Viscosity is represented by the number pair associated with the oil, such as 10/40, where 10 is the low temperature viscosity and 40 is the high temperature viscosity. (scale of 0-60, with 60 being the most viscous)
What does lube oil viscosity refer to?
The viscosity of a liquid is a measure of of "thick" the liquid is. E.g. Honey is very viscous, while water is not. In terms of motor oil, more viscous oil will thin out less at very high temperatures. Viscosity is represented by the number pair associated with the oil, such as 10/40, where 10 is the low temperature viscosity and 40 is the high temperature viscosity. (scale of 0-60, with 60 being the most viscous)
What is the definition of viscosity?
Viscosity is a fluid's resistance to flow. Fluids becomes less viscous as the liquid's temperature increases, becoming more viscous as the fluid gets cooler. A viscous fluid is sticky, thick and syrupy to a greater or lesser extent. Examples Treacle is quite viscous, but water is not. Hot engine oil is less viscous ('thinner') and runs more quickly and smoothly than cold engine oil.
What is a Brookfield Viscometer used for?
A Brookfield viscometer is used to measure the viscosity of a fluid. Viscosity refers to a fluid's tendency to resist deformation when pressure is applied to it. For example, honey is a very viscous fluid while water is not very viscous.
What is the relation between the viscosity and chemistry?
Viscosity is the thickness of a substance; how easily it flows. Molasses> very viscous Water-> not so viscous
Is copper viscous?
At Standard Temperature and Pressure, Copper is a solid metal.
Does ketchup have viscous?
By viscous, I think you mean viscosity. Viscous is a adjective referring to the thickness of a substance; therefore, yes, ketchup is somewhat viscous.
