This allows for the most reproducible results, and adequately captures the exact method used to measure this viscosity. If you have less stringent requirements, or don''t need the measurement to be reproducible elsewhere, a simplified reporting style can be implemented such as simply giving the recorded viscosity and the temperature.

4. Kinematic viscosity is the commonly used method of measuring and reporting viscosity in used-lubricant analysis, at least as far as most commercial labs are concerned. As explained in the previous paragraph, it is probably not the best method, but for historical and ease-of-use reasons it has become the dominant method. 5.
Measuring Kinematic Viscosity of Engine Oils: A Comparison of …
In terms of viscosity measurements, the following methods are also used: sensing body displacement, acoustic, and vibrational methods [8,10]. Kinematic viscosity is a measure of the resistance to flow of a fluid under the influence of gravity. Determining the kinematic viscosity is based on measuring the flow of the tested liquid through a ...

Viscosity is a measure of the resistance of a fluid which is being deformed by either shear stress or tensile stress. Viscosity describes a fluid''s internal resistance to flow and may be thought of as a measure of fluid friction. For example, high-viscosity felsic magma will create a tall, steep stratovolcano, because it cannot flow far before ...
Six Types of Devices Used to Measure Viscosity from Cole-Parmer
The consistometer doesn''t actually measure viscosity values directly: Its measurement is based on how far a fluid will flow down an incline in a certain time frame. This can be correlated to viscosity by using established standards. ... A glass capillary viscometer is used in conjunction with test methods which conform to a particular ASTM.

The dynamic viscosity of water is 1.0016 millipascals⋅second or 1.0 centipoise (cP) at 20 °C. Its kinematic viscosity is 1.0023 cSt, 1.0023×10-6 m 2 /s, or 1.0789×10-5 ft 2 /s. Liquid water viscosity decreases as temperature increases. The effect is fairly dramatic. For example, water''s viscosity at 80 °C is 0.354 millipascals⋅second.
