Dynamic viscosity of air in cp
WebThe cgs physical unit for dynamic viscosity is the poise (P). The more common unit is centipoise (cP). The more common unit is centipoise (cP). Water at 20°C has a viscosity of 0.001002 Pa·s or 1.0020 cP. WebAbsolute (dynamic) viscosity is a measure of how a fluid resists the deformation of shear stress due to its inter-molecular friction. The SI unit for absolute (dynamic) viscosity is Ns/m 2 (or 1Kg/ms). Also in common use is Poise …

Did you know?
Observed values of viscosity vary over several orders of magnitude, even for common substances (see the order of magnitude table below). For instance, a 70% sucrose (sugar) solution has a viscosity over 400 times that of water, and 26000 times that of air. More dramatically, pitch has been estimated to have a viscosity 230 billion times that of water. WebDynamic viscosity is the resistance to movement of one layer of a fluid over another. The unit of dynamic viscosity is Pa s. Usually, it is measured in centipoise (cP). Kinematic viscosity is expressed as the ratio of fluid dynamic viscosity to its density. The unit of measurement of kinematic viscosity is m 2 s -1.
