![]() ![]() Kinematic viscosity is a measure of how hard it is for a fluid to flow when it is under. If you can provide viscosity information on your fluid at 2 set points (40 & 100✬ for example) and your operating temperature then we can extrapolate the operating viscosity from this information. Table IV - Viscosities Before and After Cortina HTT 100C OCP HISC PMA PMA/OCP Before, D 445, cSt 8.49 5.77 8.77 8.73 After, D 445, cSt 8.28 6.04 7.19 7.89. The kinematic viscosity of water at 20 C is about 1 cSt (mm2/s). The metric unit is square metres per second (m2/s). Measured in stokes (St) or centistokes (cSt). Also known as the coefficient of kinematic viscosity. If there are no accessible MSDS or COSHH Sheets available then you can also find in our Tech Zone some videos of various fluids at different viscosities to provide a rough comparison.įurthermore, we also have the ability to calculate operating viscosities based on actual operational temperatures. Definition: The absolute viscosity of a fluid divided by the density of the fluid. If you have a fluid which isn’t contained within this list please send us your Material Safety Data Sheet or Chemical Safety Data Sheets with your enquiry so we can be sure to offer you a suitable pump for your requirements. Each standard is certified for Kinematic Viscosity (mm2/s,cSt), Dynamic Viscosity (cP) and Density (g/ml) at a range of temperatures. Think of a water-skier cutting through the water. ![]() To simplify, the oil’s viscosity represents the measure for which the oil wants to stay put when pushed (sheared) by moving mechanical components. Viscosity is commonly understood to be a fluids thickness or resistance to flow. There are many units of measurement when referring to viscosity, below are some simple and useful conversions to understand the thickness of various fluids:ĬSt (Centistokes) or mm²/s x 4.62 = SSU (Seybolt Seconds Universal)ĬPs (Centipoise) or mPa = cSt / S.G (Density)īelow is a table of common fluid densities and viscosities across different temperature ranges based on reliable and trusted information collated from numerous sources within the industry and our own internal knowledge and experience. If the mixed viscosity of the mold rubber you are using is higher than 15,000 cps, you may want to consider vacuum degassing the liquid mold rubber. Viscosity is the measure of the oil’s resistance to flow (shear stress) under certain conditions.
