Absolute Viscosity Of Water At Room Temperature

A water molecule contains one oxygen and two hydrogen atoms that are connected by covalent bonds.

Absolute viscosity of water at room temperature.

Karo syrup 5 000 cps. Peanut butter 250 000 cps. As a function of temperature t k. Water is a liquid at standard ambient temperature and pressure but it often co exists on earth with its solid state ice and gaseous state steam water vapor.

Castrol oil 1 000 cps. Water has a viscosity of 0 0091 poise at 25 c or 1 centipoise at 20 c. For example at room temperature water has a dynamic shear viscosity of about 1 0 10 3 pa s and motor oil of about 250 10 3 pa s. Absolute dynamic viscosities fluids liquids centipoise cp.

Pa s a 10 b t c. Latex house paint 1500 cps. Absolute or dynamic viscosity is used to calculate reynold s number to determine if a fluid flow is laminar transient or turbulent. 1 cp 0 01 poise 0 01 gram per cm second 0 001 pascal second 1 millipascal second 0 001 n s m2.

The specific gravity for water at 20 2oc 68 4of is almost one and the kinematic viscosity for water at 20 2oc 68 4of is for practical purpose 1 0 mm2 s cstokes. The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress. Sae 10 motor oil 100 cps. For further definitions go to absolute dynamic and kinematic viscosity.

Water absolute or dynamic viscosity absolute or dynamic viscosity of water in centipoises for temperatures between 32 200 o f tag search en. Kinematic viscosity of common liquids and fluids. The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress. A more exact kinematic viscosity for water at 20 2oc 68 4of is 1 0038 mm2 s cst.

It is vital for all known forms of life. Kinematic viscosity the ratio of the absolute viscosity of a liquid to its density frequently occurs in the study of viscosity and hydraulics and the term kinematic viscosity with the symbol v has been assigned to it where p is the density. Absolute or dynamic viscosity is used to calculate reynold s number to determine if a fluid flow is laminar transient or turbulent. In the metric system the unit of kinematic viscosity is the square centimeter per second or the stoke.

The dynamic viscosity of water is 8 90 10 4 pa s or 8 90 10 3 dyn s cm 2 or 0 890 cp at about 25 c. Water covers 71 of the earth s surface. Tabulated values and viscosity units conversion are given below the figures. The absolute or dynamic viscosity of water depends on the temperature as indicated below.
