High rature viscosity measurement
WebFeb 13, 2013 · Viscosity measurements up to the high shear rates represented in this study are achievable by using a die with high L/D (length/diameter) ratio (> 400) using an in-house design. The die fits into an in-house designed die holder, which can be modified to fit any commercially available capillary rheometer. WebThe resistance of a liquid to flow is called its viscosity. Viscous liquids like syrup and shampoo flow slowly. Less viscous liquids like water and gasoline flow quickly. The viscosity of a liquid usually depends on its temperature. Viscosity generally decreases as the temperature increases.

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 WebMar 30, 2024 · μ = dynamic viscosity of fluid (N s/m 2 ). dc = unit velocity (m/s). dy = unit distance between layers (m). γ = dc / dy = shear rate (s -1 ). The SI unit for dynamic viscosity is N s/m 2 or the Pascal-second (Pa s). Another unit of measurement for dynamic viscosity is poise (p), where one poise equals one-teneth N s/m 2 or 1/10 Pa s.
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.
