![]() ![]() ∴ 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. The kinematic viscosity is the measure of the internal friction force when the liquid flows under the action of gravity, and its value is the ratio of the. 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. 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. For air at sea level pressure and 20 ☌, ρ = 1.205 × 10 − 3 g cm − 3 and ν = 0.15 cm 2 s − 1. and depends on both air temperature and pressure. For air at sea level pressure and 20 C, 1.205 × 10 3 g cm 3 and 0.15 cm 2 s 1. (7.25) and depends on both air temperature and pressure. kinematic viscosity value of the fluid in Centistokes (cSt). The kinematic viscosity is an atmospheric variable defined as the ratio between the dynamic viscosity and the density of the fluid, i.e. 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. The units of dynamic viscosity are: Force / area x time. It is the resistance to the flow/movement of one layer of fluid over other. Now, we have got the complete detailed explanation and answer for everyone, who is interested! It is the measure of internal resistance of a fluid to flow under gravitational force. This is a question our experts keep getting from time to time. ![]()
