For example, lets say the density of your fluid is 1.4 g/mL, the density of your sphere is 5 g/mL, the radius of the sphere is 0.002 m, and the velocity of the sphere is 0.05 m/s. These cookies do not store any personal information. The viscosity of some fluids is dependent on the rate used to shear the material, a high rate of shear making the fluid thinner compared with the fluid that was sheared more slowly. Being able to measure the viscosity will allow to predict the behavior in a process or an application.

A range of techniques are available to measure viscosity from simple, quick-to-perform tests to more comprehensive characterisation in the form of flow curves. From the two pressure drop measurements and the flow rate reading, the fluid flow parameters are processed in the system, and the pipe line viscosity is determined.

The globe ; here 's what we saw same product produced in month. Click here to download our in-depth focus on food safety to get expert insight on mycotoxin analysis and product recalls. Rheology, or science of flow, makes it possible to know and understand, how a fluid will behave under the influence of parameters during its manufacture, its packaging, its storage, its transport, and of course its use by a whole each. Is not bent and has not any dings or dents into your sample during preparation tangential stress,,! Take the example of a large yogurt factory that uses batch processing to mature its product.

In such liquids the time delay needed for the viscosity to change suggests that a certain amount of time is needed to re-arrange or align the structural components that results in decrease in the viscosity of the test material.
