![]() These examples are programmatically compiled from various online sources to illustrate current usage of the word 'viscous.' Any opinions expressed in the examples do not represent those of Merriam-Webster or its editors. 2023 The activity can improve muscle function around the joints and encourage the body to produce more of what’s called synovial fluid, a viscous liquid that lubricates the joints. The cgs unit of viscosity is poise (P), which has been used in honour of French physiologist Jean Lonard Marie Poiseuille. Dynamic viscosity is the coefficient of viscosity as defined in Newton’s law of viscosity. Non-Newtonian fluids do not follow Newton’s law and, thus, their viscosity (ratio of shear stress to shear rate) is not constant and is dependent on the shear rate. The SI unit of kinematic viscosity is square metre per second or m 2 /s. The viscosity is independent of the shear rate. 2023 Another Cadillac exclusive is a viscous torque-converter clutch, which locks up earlier, yet more smoothly, than a conventional design does. The SI unit of viscosity is the pascal second (Pas) or kgm 1 s 1. Elise Cutts, Scientific American, 14 Mar. Erik Klemetti, Discover Magazine, 26 July 2011 Sticky and viscous like molasses, hyrax urine hardens quickly in air. 2020 Again, this may have something to do with Erebus magma being that much more viscous. 2020 To the untrained ear, a hydrothermal vent - or more precisely, a vent from the Suiyo Seamount southeast of Japan - generates a viscous, muffled burbling that recalls an ominous pool of magma. Jessica Teich, Good Housekeeping, 3 Aug. Dan Edmunds, Car and Driver, Look for rich-textured creams, thick, hydrating gels, and viscous oils. Elle Decor Editors, ELLE Decor, In either case, Performance models more effectively direct the resulting ruckus to the pavement through a new clutch-type limited-slip differential that replaces the outgoing viscous unit. ![]() The next layer is in contact with the moving layer since there is internal friction between the two layers, it also accelerates, and so on through the depth of the fluid.Recent Examples on the Web All works are linked by an expansive approach to production, pushing the material at every stage-from ashes and sand to viscous fluid to solid forms-into new visual and conceptual spheres. The lower the VI, the more the viscosity is affected by changes in temperature. It is mostly used to characterize the viscosity-temperature behavior of lubricating oils. The layer of fluid in contact with the moving plate is accelerated and starts to move due to the internal friction between moving plate and the fluid. The viscosity index ( VI) is an arbitrary, unit-less measure of a fluid's change in viscosity relative to temperature change. In the diagram, the fluid is initially at rest. ![]() Fluids have zero shear strength, but the rate at which they are sheared is related to the same geometrical factors A and L as is shear deformation for solids. The motion in the figure is like a continuous shearing motion. ![]() Care is taken to ensure that the flow is laminar, that is, the layers do not mix. Each successive layer from the top down exerts a force on the one below it, trying to drag it along, producing a continuous variation in speed from v to 0 as shown. The layer (or lamina) of fluid in contact with either plate does not move relative to the plate, so the top layer moves at speed v while the bottom layer remains at rest. The bottom plate is held fixed, while the top plate is moved to the right, dragging fluid with it. The fluid to be measured is placed between two parallel plates. \) shows how viscosity is measured for a fluid.
