High rature viscosity measurement
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. WebSep 27, 2024 · Viscosity can be measured in 1 of 2 ways: (1) as an absolute value where the physical unit is the centipoise [cP = 1N/ (M2sec)]. The viscosity of water is 0.894 cP. The viscosity of serum is ≤1.5 cP, SAE10 motor oil is 65, …

During normal operating conditions, engine … 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.
WebA typical turbine meter calibration curve illustrates the relationship between fluid flow and the K-factor (pulses/gallon). Turbine meters can be highly accurate; between 0.5-1% with some as high as 0.1% of reading (actual flow) and linearity of ±0.25% over a 10:1 flow range or ±0.15% linearity over a 6:1 range.
