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. 1 Centipoise 1 mPa s (Millipascal Second) 1 Poise 0.1 Pa s (Pascal Second) Centipoise Centistoke x Density Newtonian materials are referred to as true liquids since their viscosity or consistency is not affected by shear such as agitation or pumping at a constant temperature. Viscosity Scale Honey or Corn Syrup, 2,000 - 3,000, centipoise (cps) Molasses, 5,000 - 10,000, centipoise (cps) Chocolate Syrup, 10,000 - 25,000, centipoise. For kinematic viscosity, the SI unit is m2/s. In engineering, the unit is usually Poise or centiPoise, with 1 Poise 0.1 Pascal-second, and 1 centiPoise 0.01 Poise.
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. Units and conversion factors For dynamic viscosity, the SI unit is Pascal-second. 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. 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. Viscosity is the internal friction of moving fluid and a measurement of the resistance of a fluid deformed by shear stress.
