There are different types of rotational tests. In these tests there are two different types of test settings which can be used: In a controlled shear rate test (CSR or CR test) the speed or shear rate ...

Viscosity the most important physical property of a lubricating oil, as determines how easily the oil circulates and its load carrying capability. Maintaining the correct balance between low viscosity ...

There are few industries as demanding as the chemical and petrochemical industry when it comes to liquid flow measurement and control. Positive Displacement flow measurement devices, such as Titan ...

Viscosity is a vital quality-control parameter across a wide range of industries, especially in petroleum, where it provides essential insights into everything from crude oil to refined products.

Sound waves can measure viscosity on the fly. Though viscosity is the degree to which a fluid resists flow, it is more specifically a measure of a fluid's molecular friction. It can be a useful ...

For producers of oil-based cosmetic products, the viscosity is an essential parameter to be determined. The pure oils are used as raw materials and further checked in quality control, transported, ...

Pharmaceutical companies have increasingly focused on developing high-concentration protein therapeutics that enable patients to treat themselves at home by self injection. However, the formulation of ...

I was kind of shocked and amazed by a recent publication in NanoLetters. It seems that viscosity measurements are still difficult. In my ignorance, I had assumed that this was a solved problem. And, ...

Viscosity, or a fluid’s resistance to flow, is independent of the rate of shear or shear stress, at a given temperature, for Newtonian fluids. Non-Newtonian fluids such as polymer solutions often ...
