WebViscosity of Gases The viscosity of a gas can be thought of as a measure of its resistance to flow and is measured in the CGS unit Poise = dyne sec/cm 2. The viscosity of gases near room temperature are in the centiPoise range, so that is a commonly used unit. Gas viscosity is only weakly dependent on pressure near atmospheric pressure.
WebGasoline engine oil and diesel engine oil are classified according to GB/t14906-1994 "Viscosity Classification of Internal Combustion Engine Oils" and industrial gear oils are classified according to their kinematic viscosity at 50 °C. , while ordinary hydraulic oil, mechanical oil, compressor oil, refrigerator oil and vacuum pump oil are divided … WebKinematic viscosity can be obtained by dividing the absolute viscosity of a fluid with its mass density. In the SI the unit is m²/s. However, the commonly used measure is the stokes (or stoke) where 1 St = 10⁻⁴ m²/s. Its symbol is St. In engineering, centistokes (cSt) are usually used. 1 St = 100 cSt or 1 cSt = 10⁻⁶ m²/s. Water at 20 ...
Web5 mrt. 2024 · The kinematic viscosity is defined as. The gas density decreases with the temperature. However, The increase of the absolute viscosity with the temperature is enough to overcome the increase of density and thus, the kinematic viscosity also increase with the temperature for many materials.

A CGS unit named after Sir George Stokes is also used where one Stoke (St) = 0.0001 m 2 ·s −1. Centistokes (cSt) is often used instead with 1 cSt = 1 mm 2 ·s −1 = 10 −6 m 2 ·s −1. Conveniently, the kinematic viscosity of water at 20 °C is approximately equal to 1 cSt. pantone on illustratorWebViscosity is generally an important parameter for diesel fuel.
