"WebThe correct calculation of parameters related to viscosity depends on two criteria: The fluid does not glide along the plates but is in good contact with them. Scientifically speaking, an adhesive force operates between fluid and plates. The flow is laminar. It forms infinitesimally thin layers and no turbulence (i.e. vortices) occurs.

WebMar 25, 2024 · If the viscosity is related to the density of the fluid, then we also speak of kinematic viscosity ν (Greek small letter Nu). The unit of kinematic viscosity is m²/s. ν = η ρ kinematic viscosity [ν] = m² s The kinematic viscosity puts the viscosity of a fluid in relation to its density and is a measure of how “pasty” a fluid is. WebThe viscosity of a liquid is a measure of its resistance to flow. Water, gasoline, and other liquids that flow freely have a low viscosity. Honey, syrup, motor oil, and other liquids that do not flow freely, like those shown in Figure 7.1.1, have higher viscosities.

WebApr 12, 2010 · Viscosity is also related to a fluid’s density. Density describes the space ( volume) that is occupied by a substance’s particles and is measured in kilograms per cubic metre (kg/m 3 ). Note that this does not describe a substance’s weight.
