Definitions • viscosity (dynamic viscosity, absolute viscosity): a fluid’s resistance to deformation from shear stress • no-slip condition: fluid particles in contact with a solid boundary have the same velocity as the boundary
5 dni temu · Viscosity is a physical quantity that describes a fluid’s resistance to flow. It is a property that resists the relative displacement of the different layers of the fluid. It can be considered as the fluid friction occurring inside the fluid due to the internal friction between the molecules.
The viscosity of water at 20 °C is 1.0020 millipascal seconds (which is conveniently close to one by coincidence alone). Most ordinary liquids have viscosities on the order of 1 to 1000 mPa s, while gases have viscosities on the order of 1 to 10 μPa s.
