![]() Special consideration needs to be given during the design to ensure they remain at the correct temperature in all stages of the process. To reduce the viscosity of paste materials usually heat is applied. Some do not seek their own level or flow at all and require pressure to move them. The shorter the time it takes the easier they are to pump. Paste - some paste viscosity materials will seek their own level or flow slowly. Ketchup and mayonnaise are good examples as they appear thick but pump quite easily. ![]() Thixotropic - at a fixed temperature these reduce their viscosity with agitation or pressure increase. ![]() Newtonian - at a fixed temperature their viscosity does not change through agitation or pumping. There are several categories of fluid viscosities which include: It is usually represented in centipoise (cps) or poise (100 Centipose = 1 poise).

Our products meet strict regulatory requirements and many are are sustainable, helping protect both people and the planet. MicroCare and its sub-brands, MicroCare Medical, Sticklers and Stereze formulate and blend cleaning coating, lubricating and sterilization fluids used in the manufacture, installation and use of products in the electronics, medical device manufacturing, fiber optic, metal finishing, industrial maintenance and healthcare infection prevention industries. Some common viscosities are listed in this chart: 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. Some liquids, like pitch, glass and peanut butter, have such high viscosity they behave like solids. Fluids with low viscosity have a low resistance and shear easily and the molecules flow quickly high viscosity fluids move sluggishly and resist deformation.

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. 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. Some examples of liquids with low viscosities. ![]() Cleaning fluid viscocity plays an important role in how effective a cleaning fluid is.Īccording to Wikipedia, viscosity is the friction between the molecules of fluid. Depending on the specific situation, how viscous a liquid is can play an important role in its application. This corresponds to the informal concept of “thickness” - for example, honey is thicker and has a much higher viscosity than water. 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. It has viscosity due to the slipping of the fluid layer about. Honey is a natural product made by the honey bee. Fluid mechanics is the study of how fluids move, and one of the most important parameters of fluids is their viscosity. Viscosity Examples: Detailed Explanation Honey.
