If you are a consultant, you may get yourself listed in CSP business directory (free) or The kinematic viscosity, often represented by the greek letter and used mainly for liquids, is a measure of the viscosity in the particular situation where the fluid is flowing down because of its own weight. The general difference between the kinematic viscosity and the dynamic viscosities of fluids is like above. You may also find an expert in CSP business directory below. If you have questions or need any help, please contact our sponsor. Under GHS, a hydrocarbon shall be classified as aspiration toxicity hazard category 1 if its kinematic viscosity is less than 20.5mm2/s (20 cSts) at 40 ☌. Usually, increased temperature reduces the viscosity of a liquid and makes it more hazardous. Dynamic viscosity is the quantitative expression of fluids resistance to flow, while Kinematic viscosity is the ratio of the fluids viscous force to the. Liquids with lower viscosity are generally more hazardous because they can spread more quickly. Kinematic viscosity as a function of temperature of 6 di erent synthetic and semisynthetic oils have been considered. Water at 20 ☌ has a kinematic viscosity of about 1 cSt. Other units used include St and cSt.ġ cSt (centiStoke) = 1 mm2/s = 10^(?6)m2/s The SI unit of the kinematic viscosity is m2/s. The kinematic viscosity is the ratio between the dynamic viscosity and the density of a fluid. Density actually provides a way to convert between a kinematic and a dynamic viscosity measurement. Kinematic Viscosity is a measure of the resistive flow of a fluid under the influence of gravity. A basic difference between the dynamic and kinematic viscosity measurements is density. You can often find it in the section 9 of a safety data sheet (SDS).ĭynamic Viscosity is a measure of a liquid’s resistance to its shearing flows, where adjacent layers move parallel to each other with different speeds. Tables of the dynamic and kinematic viscosity of aqueous KCl solutions in the temperature range 25-150☌ and the pressure range 0. There are two types of viscosity: Dynamic viscosity and Kinematic viscosity. Air at 1 atm and 20 ° C (density of air is 1.204 kg/m2 kinematic viscosity is 1.516x10 m/s) flows tangentially on both sides of a thin, smooth flat plate of width 3m and of length 1m in the direction of the flow. Viscosity is the measure of a liquid’s resistance to flow. Kinematic viscosity mm 2 /s (The calculator on this site is for informative purposes only and we make no claims as to the accuracy, completeness or fitness for any particular purpose of the results produced by our calculators. ![]()
