WebJun 6, 2011 · Tables of recommended values for the viscosity of common gases as a function of temperature. Webviscosity, resistance of a fluid (liquid or gas) to a change in shape, or movement of neighbouring portions relative to one another. Viscosity denotes opposition to flow. The …
Viscosity depends strongly on temperature. In liquids it usually decreases with increasing temperature, whereas, in most gases, viscosity increases with increasing temperature. This article discusses several models of this dependence, ranging from rigorous first-principles calculations for monatomic gases, to … See more Viscosity in gases arises from molecules traversing layers of flow and transferring momentum between layers. This transfer of momentum can be thought of as a frictional force between layers of flow. Since the … See more • Viscosity index • Tribology • Transport phenomena • Molecular modeling • Intermolecular force See more The kinetic theory of gases allows accurate calculation of the temperature-variation of gaseous viscosity. The theoretical basis of the kinetic theory is … See more In contrast with gases, there is no systematic microscopic theory for liquid viscosity. However, there are several empirical models … See more 1. ^ Chapman & Cowling (1970) 2. ^ Chapman & Cowling (1970), pp. 97–98, 226–230 3. ^ Chapman & Cowling (1970), pp. 230–232 4. ^ Chapman & Cowling (1970), pp. 232–234 See more WebThe gas viscosity of difluoromethane was measured using an oscillating disk viscometer of the Maxwell type from 298.15 to 423.15 K at pressures up to 10 MPa. The results were fitted to an empirical equation as a function of temperature and density.
