Restoring of SD of parameters of stress field is based on the effect of acoustoelasticity. Its fundamental problem is determination of relationship between US wave parameters and components of stresses. To use in practice acoustoelasticity for SDS diagnosing, it is designed matrix theory [Bobrenco, 1991]. For the description of the elastic waves spreading in the medium it uses matrices of velocity v of US waves spreading, absolute A and relative... 

We begin the mathematical analysis of the model, by considering the forces acting on one of the beads. If the sample is subject to stress in only one direction, it is sufficient to set up a one-dimensional problem and examine the components of force, velocity, and displacement in the direction of the stress. We assume this to be the z direction. The subchains and their associated beads and springs are indexed from 1 to N we focus attention on the ith. The absolute coordinates of the beads do not concern us, only their displacements. 

The equation of motion as given in terms of angular momentum can be transformed into other forms that are more convenient to understanding some of the basic design components. To understand the flow in a turbomachine, the concepts of aboslute and relative velocity must be grasped. Absolute velocity (V) is gas velocity with respect to a stationary coordinate system. Relative velocity (IV) is the velocity relative to the rotor. In turbomachinery.

In Eq. (9.90), C2 is the tangential component of the absolute velocity at the exit if the flow is exactly in the blade direction. Since the slip factor is ieSs than 1, the total pressure increase will decrease according to Eq. ( 9.72) for the same impeller and isentropic flow.

Equation (9.102) gives = C2a- The axial component does not change, but when C2 > then C2 > Cj. Thus, the axial fan increases the absolute velocity of airflow. 

At the exit the absolute velocity has velocity component C2 on the large circumference parallel to the shaft of Example 3. Component is of no advantage if a duct is connected to the axial fan, since it disappears due to the friction between the walls of the duct and gas flow. 

To consider the control volume form of the conservation of mass for a species in a reacting mixture volume, we apply Equation (2.14) for the system and make the conversion from Equation (3.12). Here we select/ = pt, the species density. In applying Equation (3.13), v must be the velocity of the species. However, in a mixture, species can move by the process of diffusion even though the bulk of the mixture might be at rest. This requires a more careful distinction between the velocity of the bulk mixture and its individual components. Indeed, the velocity v given in Equation (3.13) is for the bulk mixture. Diffusion velocities, Vi, are defined as relative to this bulk mixture velocity v. Then, the absolute velocity of species i is given as... 

When more than one reaction affects the mass of the ion i in solution (e.g., dissolution and/or precipitation of heterogeneous solid assemblages homogeneous reactions in solution), the overall change in mass of component i is given by the summation of individual absolute reaction velocities Vj, multiplied by their respective stoichiometric reaction coefficients ... 

If we suppose that any particle has an absolute velocity along s equal to the velocity of light c, then this velocity will have a space component parallel to d equal to c X (d/s) and a time component equal to c X (ct/s). 

It appears therefore that if we suppose every particle to have a velocity ic along s, then its ordinary or space velocity will be d/t or v. The time component of the velocity ic is ic X (ct/s) which is equal to ic X (ct/ict) or just c.. Different observers will get different values for v, but the absolute velocity is the same for all observers.
