Viscosity is a measure of the resistance of a fluid to being deformed by either shear stress or extensional stress. The specific gravity (SG) equals the fluid density divided by the density of water (1000 kg/m^3). For low flash point lubricants when conditions prevent testing at 100°C. This formula requires you to already know the precise dynamic viscosity and density of the fluid. Below is a water viscosity to temperature chart that shows the effect of temperature on the dynamic viscosity and kinematic viscosity of water. Viscosity conventionally uses unusual units. The dynamic viscosity calculator provides the density and the viscosity of water at 20 c as follow: Dynamic viscosity = η = 1.0016 mPa.s. To put that into layman's terms, kinematic viscosity equals dynamic viscosity divided by density. If you divide kinematic viscosity by the fluid density, you get absolute viscosity. Kinematic viscosity is measured in units of (length) 2 /time - most commonly using centiStokes (cSt), where 1 Stoke = 1 cm 2 /s. ρ ρ is the density. its kinematic viscosity, ν: ν = η/ρ Note 2 to entry: where η is the dynamic viscosity coefficient.
