Fluid viscosity is an important physical property, which is, as it flows in fluid behavior. Highly viscous fluid-resistant strain, stress, and traffic is not so easy, but less viscous fluid flow easier and less stress-resistant. The two main ways to measure the dynamic viscosity and kinematic viscosity. These are inter-related, but different programs.
Dynamic viscosity, also called absolute viscosity is the most commonly used measurements. It measures the resistance of fluid flow - in other words, the internal friction of the fluid, or how easily it can deform under mechanical stress at a given temperature and pressure. Definition of dynamic viscosity of the shear stress ratio of the speed gradient. When the force is perpendicular to the liquid surface, it deforms to the side, or scissors. Mild to severe deformations of the dynamic viscosity, sometimes referred to simply as the viscosity.
Kinematic viscosity, in contrast, measures the weight of fluid flow resistance. This measure is to get fluid dynamic viscosity and dividing it by the fluid density. The higher viscosity of the liquid will be more easily under the force of gravity and a higher kinematic viscosity will be.
Dynamic and kinematic viscosity, expressed in different units of measurement. The International System of Units (SI) units of dynamic viscosity Pascal seconds. Pascals pressure measurement in this case, the fluid shear stress - in seconds to measure the time it takes to deform. Dynamic viscosity can also be measured in units called poise, and other measures for the pressure dependence of the time. A unit used to measure kinematic viscosity Stokes, or square centimeters per second, although at times square meters per second in SI units are used.
Use is necessary for dynamic and kinematic viscosity measurements of various real-world applications. For example, it is important to formulate a paint with a certain dynamic viscosity to ensure that it can be mixed and applied the correct thickness. Kinematic viscosity measurement often used in cases where the liquid to flow through a pipe or lubricate machinery like a car engine.
In today's business world, searching for answers online is another way for many QC labs. "It's a simple thing it seems the word (s) that describe if you have any questions, for example, pharmaceutical viscosity or" viscosity studies. viscometer Most manufacturers maintain web applications information that is useful in dealing with everyday issues that come up. Brookfield's web site (see Figure 2). It is not only the section that describes how to test a variety of materials, but also a "Frequently Asked Questions" or "FAQ" section, which describes how to verify that your device is properly read viscosity.
Products such as motor oil, which is a different physical conditions must be dynamic and kinematic viscosity behave correctly. Fluid viscosity, temperature and pressure changes. For example, cold air, oil thickens and becomes denser, so it flows more difficult. It is important to know the dynamic and kinematic viscosity coefficients in this situation, to predict how oil will behave at different temperatures.
