![]() ∴ C.G.S unit of kinematic viscosity is cm 2/s. Its unit is Stoke or m2/s (1 stoke = 0.0001 m2 /s). (2) Kinematic Viscosity: The ratio of dynamic viscosity to density appears frequently and this ratio is given by the name kinematic viscosity. Which of the following is kinematic viscosity?Ī common unit of dynamic viscosity is poise. Where is viscosity found?īy definition, viscosity is a type of property found in liquids and gases that measures the matter's resistance to flow or change shape. For air at sea level pressure and 20 ☌, ρ = 1.205 × 10 − 3 g cm − 3 and ν = 0.15 cm 2 s − 1. Stoke or centistoke (1/100 of a Stoke) is the unit of kinematic viscosity in kinematic viscosity. This is the amount of time it takes for an oil to flow through a capillary tube while being pushed by the force of gravity. A more exact kinematic viscosity for water at 20.2 o C (68.4 o F) is 1.0038 mm 2 /s (cSt). The dimensional formula of Kinematic Viscosity is given by, M 0 L 2 T-1. and depends on both air temperature and pressure. The fundamental units of absolute viscosity and kinematic viscosity are used to express these properties. Dimensional Formula of Kinematic Viscosity. The kinematic viscosity is an atmospheric variable defined as the ratio between the dynamic viscosity μ and the density ρ of the fluid, i.e. Now, we have got the complete detailed explanation and answer for everyone, who is interested! This is a question our experts keep getting from time to time. In the SI-system the theoretical unit of kinematic viscosity is m2/s - or the commonly used Stoke (St) where 1 St (Stokes) 10-4 m2/s 1 cm2/s Stoke comes from the CGS (Centimetre Gram Second) unit system. ![]()
