A non-Newtonian fluid is a fluid whose flow properties are not described by a single constant value of viscosity. Many polymer solutions and molten polymers are non-Newtonian fluids, as are many commonly found substances such as ketchup, starch suspensions, paint, blood and shampoo. In a Newtonian fluid, the relation between the shear stress and the strain rate is linear, the constant of proportionality being the coefficient of viscosity. In a non-Newtonian fluid, the relation between the shear stress and the strain rate is nonlinear, and can even be time-dependent. Therefore a constant coefficient of viscosity can not be defined. A ratio between shear stress and rate of strain (or shear-dependent viscosity) can be defined, this concept being more useful for fluids without time-dependent behavior.

The relationship between shear rate and viscosity?
Shear rate and viscosity are related to each other. According to shear rate and viscosity we can classifying the materials especially paints. Fluids are divided into two types like 1.NEWNONION FLUIDS and 2.NON NWETONINON FLUIDS based on shear rate and viscosity. In fluids if there no change in viscosity with respective shear rate, such type fluids are known as nwetonion fluids. Viscosity changes with respective shear rate such type of fluids are known as non nwetonion fluids.
Why liquidgas or plasma considered fluids?
Fluids are substances that flow. Liquids flow, gases flow, and ionized gases (plasmas) flow. Thus, they are all fluids.
What mixture of fluids?
What happens when you create a mixture of fluids depends on what the fluids are. In many recipes, two or more liquids are commonly mixed in order to create a delicious treat.
What is used to measure fluids?
You can measure fluids in beakers, graduated cylinders or liquid measuring glasses. It depends on what you're measuring and why.
What are the different types of sterile body fluids?
I think Pleural (lungs), Peritoneal (abdomen), and Pericardial (heart) fluids are normally sterile. Also, synovial (joints) and cerebral spinal fluids.
How would you use tissue in a sentence?
In some plants vascular tissue help to transport fluids in it.
How can you use plasma in a sentence?
During the war, plasma was used to provide fluids for wounded soldiers.
How would you use vascular tissue in a sentence?
In some plants vascular tissue help to transport fluids in it.
Various drilling mud have the same apparent viscosity at 1022sec-1 but the effective viscosity at other shear rates may vary widely Explain?
Drilling mud is a nonnewtonian fluid. It's a thixotropic fluid and it's apparent viscosity is a function of shear rate and time so at various shear rate and times you will have various viscosities. The molecular structure of these fluids breaks during tention.For further informations you can refer to rheology or fluid mechanics books.
What is the medical term meaning fluids intravenously?
The medical term for fluids administered intravenously is "intravenous fluids" or "IV fluids." These fluids are given directly into a vein to help maintain hydration, replace lost fluids, deliver medications, or provide nutrition.
What are second grade fluids?
Second grade fluids are fluids that flow through a parallel plate. The fluids go through the parallel plate horizontal.
What is a sentence for transmitted?
We have transmitted the signal.She transmitted the disease to her lover.
Can you make a sentence using the word digest?
The human body is able to digest food because it has body fluids, such as saliva, and acids that breaks down the food so it can be absorbed.
What industries use fluids?
depends what fluids, but all industries use some sort of fluids in most proccesses
What fluids are studied in chemistry tests?
All the types of fluids !
What are food fluids?
Food fluids are the juices from the food as it is cooking.
When was Physics of Fluids created?
Physics of Fluids was created in 1958.
