Massey, B S (1983) Mechanics of Fluids, fifth edition, ISBN 0442305524.Viscosity Page A table of items sorted by viscosity in centipoise (cP).Interactive Kinematic Viscosity Conversion Table - convert selected unit to all other units of kinematic viscosity.Online Kinematic Viscosity Converter - convert between various units of kinematic viscosity, such as square meter per second, square foot per second, stokes, and so on.Interactive Dynamic Viscosity Conversion Table - convert selected unit to all other units of dynamic viscosity.Online Dynamic Viscosity Converter - convert between various units of dynamic viscosity, such as Ppascal second, kilogram-force second per square meter, pound-force second per square inch, poise, and so on.Which is only slightly simpler than the equivalent equation in terms of viscosity: For two components (a and b), the fluidity of a solution of a and b is: The concept of fluidity can be used to determine the viscosity of an ideal solution. Fluidity is seldom used in engineering practice. The reciprocal of viscosity is fluidity, usually symbolised by φ (=1/μ) or F (=1/η), depending on the convention used, measured in reciprocal poise ( cm ![]() The dynamic viscosities of liquids are typically several orders of magnitude higher than dynamic viscosities of gases.Ī Data from CRC Handbook of Chemistry and Physics, 73rd edition, 1992-1993.įluids with variable compositions, such as honey, can have a wide range of viscosities.Ī more complete table can be found here Can solids have a viscosity? Viscosity tends to fall as temperature increases (for example, water viscosity goes from 1.79 cP to 0.28 cP in the temperature range from 0 ☌ to 100 ☌) see temperature dependence of liquid viscosity for more details. ![]() Viscosity is independent of pressure (except at very high pressure) and.This leads to an additional contribution to the shear stress though the exact mechanics of this are still controversial. In liquids, the additional forces between molecules become important. ![]()
