WebThe value of the dynamic viscosity coefficient is found to be a constant with pressure but the value depends on the temperature of the gas. For air, D. M. Sutherland provides an equation for the dependence on … Observed values of viscosity vary over several orders of magnitude, even for common substances (see the order of magnitude table below). For instance, a 70% sucrose (sugar) solution has a viscosity over 400 times that of water, and 26000 times that of air. More dramatically, pitch has been estimated to have a viscosity 230 billion times that of water.
