Standard Practice for Calculating Viscosity Index from Kinematic Viscosity at 40 and 100°C1 This standard is issued under the ﬁxed designation D 2270; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. ) A stoke equals 1 cm. Its principle of operation is based on comparing the viscosity of the test fluid with a reference fluid of known viscosity. How to use Viscosity - Dynamic Converter Select the unit to convert from in the input units list. 3, 4 It depicts the required minimum (rated) viscosity v 1 as a function of bearing dimension and shaft speed. Viscosity numbers range from one to millions of centipoise(cps), When it comes to polyurethanes and epoxies, keep in mind that temperature can have a major impact on a resin's viscosity. Viscosity Converting Chart A converting table between viscosity units like Centiposes, milliPascal, CentiStokes and SSU Centipoise (CPS) Millipascal (mPas) Poise (P) Centistokes (cSt) Stokes (S) Saybolt Seconds Universal (SSU) 1 0. The theoretical unit is the Stokes. 01 Water & Sediment, Volume % D 2709 0. More dramatically, pitch has been estimated to have a viscosity 230 billion times that of water. A set of. 6 cSt PAO, plastic compatible, light viscosity oil for im-proved low torque start-up. Most ordinary liquids have viscosities on the order of 1 to 1,000 mPa s, while gases have viscosities on the order of 1 to 10 μPa s. See also VISCOSITY. There are two types of viscosity: a) dynamic viscosity, expressed in Pa. How Is Viscosity Measured? There are several different methods to measure both dynamic and kinematic viscosity. 86 fluid specific gravity. This addition will double the current capacity for high viscosity products and give AB Specialty Silicones the capability to produce materials with viscosity up to ~500,000 centipoise. Density actually provides a way to convert between a kinematic and a dynamic viscosity measurement. Difference of Viscosity for Silicone Oil (From 0. and used to measure the viscosity of n-octane for temperatures to 500. k is a device constant (in m 2 /s 2 or mm 2 /s 2) that comes with the calibration document of the. The unit of dynamic viscosity is the Poiseuille (=Pa·s). The calculated data should be used as reference information only. VISCOSITY CONVERSION TABLES by NORCROSS CORPORATION® 255 Newtonvill e Avenu e, Newton, MA 02458 USA Ph one: 617. 3 of the Heat Exchanger Design Handbook, 1986, by C. Kinematic Viscosity Formula Questions: First calculate the density mass of mercury using the formula ρ = mass/volume. The tools shown below were developed to assist engineers in the preliminary selection of suitable fluid-handling technologies.
