Dynamic viscosity is a material property which describes the resistance of a fluid to shearing flows. It corresponds roughly to the intuitive notion of a fluid's 'thickness'. For instance, honey has a much higher viscosity than water. Viscosity is measured using a viscometer. Measured values span several orders of magnitude. Of all fluids, gases have the lowest viscosities, and thick liquids. Learn what viscous means with clear definitions, pronunciation, synonyms, and real-world examples. Simple explanations to help you use viscous correctly. Synonyms for VISCOUS: thick, sticky, syrupy, heavy, viscid, ropy, creamy, turbid; Antonyms of VISCOUS: thin, runny, watery, fluid, liquid, soupy, flowing, weak A viscous fluid is any liquid or gas that resists flowing freely, caused by internal friction between its molecules as they move past each other. The higher the viscosity, the slower and thicker the fluid behaves. Honey is a classic example: pour it from a spoon and it moves sluggishly compared to water, which splashes and spreads almost instantly. That resistance you can see and feel is. The meaning of VISCOUS is having a thick or sticky consistency : viscid. How to use viscous in a sentence. VISCOUS definition: 1. A viscous liquid is thick and sticky and does not flow easily. 2. A viscous liquid is thick and…. Learn more. Learn the difference between “vicious” and “viscous” to use each word correctly and improve clarity, precision, and impact in your writing. VISCOUS meaning: 1. A viscous liquid is thick and sticky and does not flow easily. 2. A viscous liquid is thick and…. Learn more. VISCOUS definition: of a glutinous nature or consistency; sticky; thick; adhesive. See examples of viscous used in a sentence. Viscosity is the material property which relates the viscous stresses in a material to the rate of change of a deformation (the strain rate). Although it applies to general flows, it is easy to visualize and define in a simple shearing flow, such as a planar Couette flow.
