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. Measured in stokes (St) or centistokes (cSt). Also known as the coefficient of kinematic viscosity. The kinematic viscosity is the dynamic viscosity divided by the density of the fluid. Kinematic Viscosity Definition: The absolute viscosity of a fluid divided by the density of the fluid.

The unit centiPoise = 0.001 Pa s and is is sometimes written mPa s. 1 cP 0.001 Pa s 0.01 P 0.01 g/(cm sec) 6.72197x10-4 lb/(ft s) 2.4191 lb/(ft h) 1 lb/(ft h) 0.00027778 lb/(ft s) 0.00041338 Pa s 0.0041338 P. Viscosities of common liquids by type of liquid Approximate Viscosities of Some Common Liquids click here to download in pdf format We provide representation in the UK for specialist pump manufacturers, with particular emphasis on sealless leak free pump technology. As you can see, water viscosity decreases as temperature increases, and the relationship is stronger for lower temperatures. 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☌. Water viscosity-temperature chart that displays the dynamic and kinematic viscosities as well as the density of water at temperatures ranging from 0C to 370C. 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. A circular disc is rotating about its own axis.

Viscosity has the SI units Pascal seconds (Pa s) which is called the Poiseuille. The coefficient of viscosity of water is 10-3 Pa s. In addition, reading for viscosity was taken three. The calculator below can be used to calculate the liquid water dynamic or kinematic viscosity at given temperatures. Viscosity of Liquids and Gases Viscosity of Liquids and Gases Liquids nanofluid viscosity was determined by the rotational speed of spindle and measurement was in centipoise (cP).
