Effective Viscosity for Non-newtonian fluids is usally defined to calculated for pressure losses. See Bingham or Power law fluids characteristics.
All fluids have a 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.
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.
sity hydraulic fluids
Viscosity is a fluids resistance to flow. A high viscosity fluid would be thick, a low viscosity fluid would be thin.
Flow
Certain fluids, especially liquids, do exert internal friction. This property of the fluid is called viscosity. Rheology is known as the study of viscosity.
er...what fluids?
determination of viscosity of medium.
Some fluids are more denser than other fluids. For example, shampoo is more denser than Ketchup or oil or water. Therefore, it has a higher viscosity! The thick/denser/sticker a fluid is the higher the concentrtation of viscosity. Here is a range of some fluids put from high viscosity to low concentration of viscosity: 1: Shampoo 2: Ketchup 3: Corn oil 4: Water Water has a really low concentration of viscosity.
A measure of a fluids resistance to flow. For more information please see the wikipedia article about viscosity.
Viscosity is the measure of a fluids ability to flow, it is measured in pascal-seconds(this link might help)http://en.wikipedia.org/wiki/Viscosity#Units
