Absolute Viscosity meaning, synonyms, antonyms, translation, and use cases

Absolute viscosity

In today’s word for the day, we will be giving you highlight on the meaning of absolute viscosity, its synonyms, antonyms, translation, and use cases.

Meaning

The absolute viscous force impeding fluid movement is calculated using the concept of absolute viscosity. The relationship between the viscous force preventing the commencement of fluid flow and the fluid’s gradient in velocity has been established by Newton’s law. According to Newton’s law, the magnitude of the viscous force that opposes fluid motion is inversely proportional to the velocity gradient at the place in question and flows in the opposite direction. Take a look at the following illustration of the fluid velocity profile near a stationary wall.

To distinguish between absolute viscosity and kinematic viscosity, this definition is the same as the word “viscosity” alone. The proportion of a fluid’s shear stress to velocity gradient is shown by this. It is the internal flow resistance of a fluid. The poise serves as its measurement unit. Kinematic viscosity is calculated by dividing the dynamic viscosity by the fluid’s density. Dynamic viscosity is another name for this. Fundamental units are used to express both kinematic viscosity and absolute viscosity. Saybolt viscosity and empirical viscosity are both measured in arbitrary units of time, typically seconds.

Absolute viscosity – coefficient of dynamic viscosity – is a measure of internal resistance. Dynamic (absolute) viscosity is the tangential force per unit area required to move one horizontal plane with respect to another plane – at a unit velocity – when maintaining a unit distance apart in the fluid.

The degree to which a fluid resists flowing in reaction to an external force is measured by its absolute viscosity. The metric applies to applications like forcing oil through a tube or pushing an object through fluid with the force of a motor-powered spindle. The density of the fluid is not a consideration. The fluid’s internal resistance is estimated, and the shear resistance is proportional to the applied force. A fluid’s density is multiplied by its absolute or kinematic viscosity in order to measure it precisely when subjected to gravity. To determine kinematic viscosity, divide the absolute value by the fluid’s density.

Absolute viscosity measurements are made for quality control, study into the properties of grease for lubricating machinery, and research into other fluids, including oils. In addition to using on-site Viscometers and laboratory measurements, absolute or dynamic viscosity is also utilized to assess oil. For Newtonian fluids, which have a constant viscosity regardless of the shear rate, it is computed by multiplying the fluid’s kinematic viscosity by its specific gravity.

Viscosity

Viscosity is the ability of a fluid (liquid or gas) to resist changing its shape or allowing nearby parts to move in relation to one another. Viscosity is a sign of flow resistance. The fluidity, a metric indicating the ease of flow, is the reciprocal of viscosity. For instance, molasses is more viscous than water.

Viscosity can be thought of as internal friction between the molecules; this friction prevents the development of velocity disparities within a fluid since a section of a fluid that is compelled to move carries along nearby parts to some extent. When fluids are employed as lubricants and carried in pipes, viscosity has a significant role in defining the forces that must be overcome.

It regulates the liquid flow during procedures like spraying and injection,molding, and surface coating.

The dimensions of dynamic viscosity are force × time ÷ area. The unit of viscosity, accordingly, is newton-second per square meter, which is usually expressed as pascal-second in SI units.

Synonyms

  • coefficient of viscosity
  • dynamic viscosity
  • viscosity

Antonyms

  • Kinetic Viscosity

Translation

Spanish- Viscosidad absoluta

Greek- Απόλυτο ιξώδες

Latin- Viscositas absoluta

French- Viscosité absolue

Portugese- Viscosidade absoluta

Use cases

  • The dynamical system is determined by travelling-wave solutions of the associated absolute viscosity equation.
  • An alternative way of deriving a cutoff for (1.5) at high frequencies is to retain the effect of absolute viscosity.
  • Towards the end, the absolute viscosity is taken away and an external force is applied to get the particles moving again.
  • In the viscous-convective range the absolute viscosity plays a dominant role but the diffusion can be neglected.

Frequently Asked Questions

What is dynamic or absolute viscosity?

Dynamic viscosity, evaluates the internal resistance of a fluid to flow; in contrast, kinematic one describes the ratio of dynamic viscosity to density.

Is viscosity and absolute viscosity same?

Dynamic viscosity is the measurement of the fluid’s internal resistance to flow while kinematic viscosity refers to the ratio of dynamic viscosity to density.

What are the two types of viscosity?

Viscosity is the measure of a liquid’s resistance to flow. There are two types of viscosity: Dynamic viscosity and Kinematic viscosity.

What is called dynamic viscosity?

The dynamic viscosity of a fluid is the measure of its resistance to flow when an external force is applied.

What are the 2 methods for measuring viscosity?

Capillary Viscometer: One of the oldest methods of measuring viscosity, the capillary Viscometer measures the time between the volume of liquid/sample to pass through the length of the capillary tubes. Rotational Viscometer: Measures the torque required to revolve an object within the volume of liquid.

What are the 4 factors that affect viscosity?

The viscosity of a material is affected by temperature, pressure, nature of fluids, velocity gradient, etc.

What does viscosity depend on?

The viscosity of a liquid, usually depends on its temperature. Viscosity generally decreases as the temperature increases. Viscosity generally increases as the temperature decreases. The viscosity of a liquid is related to the ease with which the molecules can move with respect to one another.

Video explanation of Absolute viscosity

This will give you a further explanation of the meaning of viscosity and absolute viscosity.

Summary

The fundamental absolute viscosity test evaluates the time required to draw a given volume of asphalt binder up through a capillary tube using vacuum, under precisely regulated vacuum and temperature conditions.

Although measuring viscosity at just one temperature is an improvement over the penetration test, dynamic viscosity still does not accurately represent the consistency of an asphalt binder under the anticipated range of construction and service conditions.
