High rature viscosity measurement
Webmeasure of product consistency and quality. Another reason for making flow behavior studies is that a direct assessment of processability can be obtained. For example, a high viscosity liquid requires more power to pump than a low viscosity one. Knowing rheological behavior, therefore, is useful when designing pumping and piping systems.

WebIn general, viscosity depends on a fluid's state, such as its temperature, pressure, and rate of deformation. However, the dependence on some of these properties is negligible in … WebMar 4, 2024 · Viscosity is a measure of a fluid’s resistance to flow. It can also be thought of as a measure of a fluid’s thickness or its resistance to objects passing through it. The greater the resistance to flow, the higher the viscosity, so in the previous example, the syrup has a higher viscosity than water. 00:00 00:00 An unknown error has occurred
WebAug 23, 2024 · Viscosity can also be measured by applying oscillating vibrations to the sample and monitoring the damping effects of the fluid. These can be assessed by monitoring power input, the decay time of oscillations, or changes in the resonated frequency. Microfluidic Rheometers WebMaterials with high viscosities or broad MWD are useful in processes such as extrusion blow molding, blown film, profile extrusions, etc., where an extrudate must be somewhat self …
