Feb 2, 2011 · Thermodynamic properties of liquid and gaseous air. The enthalpy is taken as zero at an arbitrary point. The entropy is taken zero for the solid air at 0K. Air is a mixture mainly consisting of diatomic gases. Therefore its heat capacity at close to normal temperatures and pressures may with good accuracy be taken equal to. where.
The 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 temperature T: mu = mu0 * ((T / T0)^1.5) * ((T0 + 198.72) / (T + 198.72))
Jun 26, 2024 · where coefficient \(\mu\) is the dynamic viscosity. This equation can be expressed in terms of shear stress, \(\tau = F/A\). Thus expressed in differential form for straight, parallel, and uniform flow, the shear stress between layers is proportional to the velocity gradient in the direction perpendicular to the layers:

The dynamic viscosity (m) is the coefficient of proportionality so that . t = m (dV/dy) Unlike a solid, a fluid deforms continuously under the action of a shear stress. A non-Newtonian fluid is a fluid where the shear stress is not linearly proportional to the rate-of-strain.
Jun 24, 2024 · Dynamic viscosity of air. A dynamic viscosity (or absolute viscosity) is generated if we have different surfaces of air molecules moving parallel to the object's surface. This results in a shear force. To overcome the resistance of the fluid, an external force F F must be applied per unit of moving surface.
