Oil has more viscocity.8 answers Top answer: First of all Definition: What is viscosity A Viscosity is a measure of resistance between.

The absolute viscosity of all fluids is practically independent of pressure for the range that is ordinarily encountered in engineering work. Viscocity is the internal friction of the fluid.

In easy meaning, it is like a frictional force in a fluid which. In common vernacular, a liquid is said to be “viscous” if its viscosity is substantially greater than that of water, and is described as “mobile” if the viscosity is noticeably less than water.It is defined as the ratio between, dynamic viscosity to the density of a fluid. The viscosity of a fluid means the resistance of the fluid to shear or angular deformation. If viscosity is too low at high temperatures, it can't be used for lubrication. If the viscosity of a fluid is too high at low temperatures, it cannot be pumped. Fast-moving liquids like water have low viscosity and slow-moving liquids like honey have high viscosity. Some liquids, like pitch, glass and peanut butter, have such high viscosity they behave like solids. Viscosity is the resistance produced in a liquid to its flow. Fluids with low viscosity have a low resistance and shear easily and the molecules flow quickly high viscosity fluids move sluggishly and resist deformation. Fluid Viscosity, sometimes referred to as dynamic viscosity or absolute viscosity, is the fluids resistance to flow, which is caused by a shearing stress. Pressure or energy (“stress”) is needed to overcome the friction between the faster-moving fluid and the more slowly moving layers. This is because of the friction with the walls. Like friction between moving solids, viscosity transforms kinetic energy of (macroscopic) motion into heat energy.

For example, when a fluid flows through a tube, the fluid will move more quickly near the center of the tube axis but move more slowly along the walls of the tube. Viscosity is, essentially, fluid friction.

Considered two layers of fluid which are at a distance dy apart. There is a rule of thumb in the paint industry that a viscosity of approximately 100 cps (1 P, 0.1 Pas) provides acceptable spraying, brushing, or roll coating. In contrast, the kinematic viscosity of oil is its resistance to flow and shear due to gravity and it is measured with SI units of m 2 /s. The absolute viscosity of oil is its resistance to flow and shear due to internal friction and it is measured with SI units of Pa·s. In simple language, it is defined as the property of fluid which offers resistance to flow. Oil viscosity is typically measured and defined in two ways, either based on its absolute viscosity or its kinematic viscosity. A fluid with a low viscosity is said to be 'thin,' while a high viscosity fluid is said to be 'thick.' It is easier to move through a low-viscosity fluid (like water) than a high-viscosity fluid (like honey). This corresponds to the informal concept of “thickness” - for example, honey is thicker and has a much higher viscosity than water.Īccording to Wikipedia, viscosity is the friction between the molecules of fluid. What is Viscosity Viscosity is a property of a fluid which offers resistance to flow of one layer of a fluid over another adjacent layer of fluid. Viscosity is a measurement of how resistant a fluid is to attempts to move through it. Chemists have a slightly different feel for the phenomenon viscosity is defined as its resistance to gradual deformation. Most people think of “viscosity” in terms of a fluid’s ability to flow. Motor oil viscosity grades are based on a scale developed by the API. Fluid mechanics is the study of how fluids move, and one of the most important parameters of fluids is their viscosity. What Do Oil Viscosity Numbers Mean Viscosity is the resistance to flow of a fluid.
