Dimensions: L 2 t-1. 1.8 .
Certain substances of variable composition or with non-Newtonian behavior are not assigned precise values, since in these cases viscosity depends on additional factors besides temperature and pressure. Kinematic viscosity can be obtained by dividing the absolute viscosity of a fluid with the fluid mass density like ν = μ / ρ (2) (1968) Thermophysical properties of liquid air and its components.
The increase in temperature for the fluid deliberate the bonds between molecules.

For instance, a 70% sucrose (sugar) solution has a viscosity over 400 times that of water, and 26000 times that of air. a = 0.555T o + C b = 0.555T + C. where μ = viscosity in centipoise at input temperature T μ o = reference viscosity in centipoise at reference temperature T o T = input temperature in degrees Rankine T o = reference temperature in degrees Rankine C = Sutherland's constant
It can also be thought of as a measure of a fluid’s thickness or its resistance to objects passing through it. Online Air Viscosity Calculator. s. The following table illustrates the range of viscosity values observed in common substances. For air and . The greater the resistance to flow, the higher the viscosity, so for example, syrup has a higher viscosity than water. More dramatically, pitch has been estimated to have a viscosity 230 billion times that of water. While the coefficient of viscosity of gases will increase with the increase in temperature. The calculator below can be used to calculate air dynamic or kinematic viscosity at given temperatures and atmospheric pressure. Formulas for Viscosity. K. Additional information about air properties can be found in the following literature: Handbook, edited by V. P. Glushko (1978) "Nauka" Publishing House, Moskow (in Russian). The output dynamic viscosity is given as Pa*s, N*s/m 2, cP, mPa*s, lb f *s/ft 2 and lb m /(ft*h), while the … The viscosity on this page is the dynamic (absolute) viscosity. ( 1. Typical values: for water is 1.14 × 10-6 m 2 s-1, and for air is 1.46 × 10-5 m ... Viscosity is a measure of a fluid’s resistance to flow. Kinematic viscosity is the ratio of - absolute (or dynamic) viscosity to density - a quantity in which no force is involved. Additional information about air properties can be found in the following literature: Handbook Thermophysical Properties of Gases and Liquids, edited by N. B. Vargaftic (1972) "Nauka" Publishing House, Moscow (in Russian). (But note that kinematic viscosity is often measured in stokes (St); 104 St = 1 m 2 s-1.)
( 1. This equation can be expressed in terms of shear stress.

Phillips (1912) plotted temperature versus viscosity for different isobars for propane, and observed a similarity between these isobaric curves and the classic isothermal curves of the surface. A. and Rabinovitch, V. A. Kinematic viscosity = Dynamic viscosity / Fluid mass density The equation is written ν = η / ρ Standarts Publishing House, Moscow (in Russian).
