Cavity depth

Thus for any plastic where the Power Law constants are known, the clamping force can be calculated for a given radius, R, cavity depth, H, and fill time, /. 

The results also show that the normalized slip length and the average friction factor-Reynolds number product exhibit Reynolds dependence. Furthermore, the predictions reveal that the impact of the vapor cavity depth on the overall frictional resistance is minimal provided the depth of the vapor cavity is greater than 25% of its width. 

In passing, we again touch upon some geometrical facts. The diameter of the y-CD is 8.5o-9 A, which is about twice as large as that of the a-CD. The cavity depth is 7 A for all a, ft and y-CD, and almost equals the length of two ethylene glycol units. Molecular models show that the y-CD cavity is wide enough to accommodate two PEG chains, but the a-CD cavity is too narrow to make this possible. 

Kondo and co-workers have studied through-mask deposition in the convective regime experimentally for both low [141] and high [142] Peclet numbers. They have also developed a numerical model which incorporates fluid flow [143], Their Peclet number is defined in terms of the cavity depth and has the same form as Eq. (6.12). They considered the effects of cavity geometry as determined by aspect ratio and sidewall angle. 

Figure 3.5 X-ray structure of human Sirt2 in complex with NAD (predicted by docking). The molecular surface of the protein is colored according to the cavity depth.

Firstly, electrodeposition makes it possible to fill lithographically defined cavities with nanometer-scale fidelity. This pattern replication capability has been vividly demonstrated in numerous cases [6], even where the cavity depth significantly exceeds its width. Secondly, higher rates of metal deposition can typically be achieved...

Beam Penetration and Material Removal. Welding with electron, plasma, or laser beams can be modeled by considering the movement of a vertical cavity (along with the surrounding molten film) through the material to be joined (Fig. 18.7). The cavity depth-to-width ratio is usually about 10, and, to first approximation, the outer boundary of the molten liquid can be represented by a cylinder whose surface is at the melting temperature Tm. 

Typical cyclodextrins contain 6-8 glucose units. The rings are cone-shaped with a cavity depth of 0.7-0.8 nm. However, much larger rings have also been derived. They are denoted... 

The curing pressures required for TSs depends on the formulation of the compound. With CM, the cavity depth can have a significant effect on pressure, as well as on the benefits of using preheated rather than cold material delivered into the cavity (Table 6-3).

Fig. 5.3 shows a diagram of the impedance tube designed for the ISO 10534.2 implementation, where the test specimen thickness is 21 and the back cavity depth (the distance between the back surface of the specimen and the rigid termination) is L. The specific acoustic impedance at the front surface of the test specimen can be determined by (ISO Standard, 10534-2, 1998) ...

Land lengths are minimal so that shear rates are minimised, i.e., total channel depth is the sum of the opposite cavity depths (Figure 9.10). 

Materials of a high bulk factor, such as the fabric-filled type, which have a factor of approximately 8 1 are easily loaded into the powder cavity. A suitable powder cavity depth calculation, and one which has been frequently used by the author, is based on the following formula ...
