Thus, an understanding of liquid and gas viscosity is essential for engineering a chemical process. The viscosity of gases played an important role in the historical development of the kinetic theory of gases (see Keith J.

One of the c o-authors, Professor Viswanath, co-authored a book jointly with Dr. Natarajan “Data Book on the Viscosity of Liquids” in which mainly presented collected and evaluated liquid viscosity data from the literature.5/5(3). Viscosity 5 Viscosity coefficients Viscosity coefficients can be defined in two ways: • Dynamic viscosity, also absolute viscosity, the more usual one (typical units Pas, Poise, P); • Kinematic viscosity is the dynamic viscosity divided by the density (typical units m2/s, Stokes, St). Viscosity is a tensorial quantity that can be decomposed in different ways into two independent File Size: 2MB.

The book further demonstrates how to . The correlation of Carr et al. [ 70] is often used to estimate the natural gas viscosity, particularly for gases containing significant amounts of non-hydrocarbon components. It initially estimates the gas viscosity at the atmospheric pressure and the prevailing temperature, μ h = [ × 10 − 5 − × 10 − 6 S g] (T − ) + 8. Viscosities of fluids change over many orders of magnitude. The viscosity is a strong function of temperature and increases with temperature for gaseous systems at low density, while the viscosity usually decreases with increasing temperature in liquids. Extensive data on viscosities of pure gases and liquids are available. Table shows some experimental values of viscosities . Viscosity is not a strong function of pressure, hence the effects of pressure on viscosity can be neglected. However, viscosity depends greatly on temperature. For liquids, the viscosity decreases with temperature, whereas for gases, the viscosity increases with temperature.

More these forces more will be these molecules denying to flow. Hence more is the resistance to flow,which results more viscosity. Now if u i. Viscosity of Gases The viscosity of a gas can be thought of as a measure of its resistance to flow and is measured in the CGS unit Poise = dyne sec/cm 2. The viscosity of gases near room temperature are in the centiPoise range, so that is a commonly used unit. Gas viscosity is only weakly dependent on pressure near atmospheric pressure.
