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. Have any questions Talk to one of our experts by starting a chat or by calling our toll free number: 1-85. The grade comparison chart below is a general guide that. This comparative viscosity chart shows the relationship between the various viscosity grading systems (viscosities are related horizontally). On the other hand, the kinematic viscosity tells about the speed the fluid reaches when a particular force is applied to the fluid. The term viscosity refers to the thickness or flow-ability of a liquid. Viscosity classification systems provide a uniform and common basis for designating lubricants. When choosing between the two viscosities, it is worth noting that dynamic viscosity tells us about the force required to move the fluid at a certain speed. The larger the force or stress needed to move the plate, the more viscous the fluid is. The viscosity of water decreases smoothly from the freezing point while the density remains essentially constant except for the small maximum in density near 4☌. In cgs units the unit is called the centistoke. The kinematic viscosity is the dynamic viscosity divided by the density of the fluid. One major difference between the two are in the additives they use. While many motorists may assume SAE 90 gear oil is thicker than SAE 40 or 50 engine oil, their viscosities are the same, as this gear oil viscosity chart shows. Viscosity and Flow - Friction loss in steel pipes for. Viscosity - Converter Chart - Convert between viscosity units like Centiposes, milliPascal, CentiStokes and SSU. The unit centiPoise = 0.001 Pa s and is is sometimes written mPa s. Engine Oil: Viscosity Comparison Gear oil differs from engine oil. Kinematic - Vicosity is a fluid's resistance to flow and can be valued as dynamic (absolute) or kinematic. Viscosities of UCON products are virtually unaffected by high rates of shear. VISCOSITY COMPARISON CHART Material Viscosity (centipoise) Water 70F 1-5 Blood or Kerosene 10 Anti-Freeze or Ethylene Glycol 15 Motor Oil SAE 10 or Com Oil 50-100 Motor Oil SAE 30 or Maple Syrup 150-200 Motor Oil SAE 40 or Castor Oil 250-500 Motor Oil SAE 60 or Glycerin. The Poise is used in the table because of its more common usage. More commonly used is the dyne sec/cm 2 which is called Poise. They show less change with temperature than petroleum oils, because of their higher viscosity indices. Viscosity has the SI units Pascal seconds (Pa s) which is called the Poiseuille. These viscosities are at 20☌ except for the blood and blood plasma which are at body temperature, 37☌, and for steam which is at 100☌. Viscosity UCON fluids and lubricants are commercially available in a series of viscosities ranging from 12 to more than 65,000 centistokes at 40☌. Viscosity has the SI units Pascal seconds (Pa s) which is called the Poiseuille. Viscosity of Liquids and Gases Viscosity of Liquids and Gases Liquids
