The probabihty distribution/(u,s,f) for the local segment distribution is related to the contribution from the ensemble of segments at s to the total stress. It is calculated self-consistently from the survival probabihty function by letting the surviving tube segments be deformed by the total deformation tensor over their lifetimes, Eftt k...

The initial region ends, when both boundary layers 2 and 3 contact each other. Its length X0 reduces with increase in the EPR density (3.36). The velocity distributions U(z) and V(z.) across the EPR vary with A. It was discovered, however, that two profiles obtained for A and A2 can be brought together if we refer them to the corresponding Xj and xr More precisely, this similarity law for the initial region means that the following dimensionless variables suit better than (3.32) ... 

The problem of mean value with regard to the dispersed droplet EPR (3.115) sounds as the following to find three coefficients Amean, Bmea , and crmean which determine the monodisperse EPR flow (3.85) and provide the velocity distributions U(x, z) and V(x,z) as close as possible to those of the multidisperse flow (3.115), for which the spectral coefficients A(r), B(r), and cr(r) are known. 

For the given parameters (3.138), the model predicts all the aerothermal profiles in the main flow region, i.e. the air velocity profile U(z) and the vapour concentration E(z), droplet velocity distribution u(z) and the vapour concentration near their surfaces e(z) which is in an empirical relation (3.94) with the droplet temperature t. The approximate formulas were found as...

To emphasize again, the preceding arguments are useful only in identifying systems in which flow will occur as a consequence of variations in the hydrostatic pressure that cannot be balanced by a body force. To analyze any details of the motion, we would have to solve the equations of motion to determine the velocity distribution, u(x, t), and the pressure p(x, t), which would be modified from the hydrostatic form because of the motion of the fluid. 

Note that, in practice, the mean and variance of the distribution (/u. and a) are not precisely known, and are estimated from n measurements. As such the lower-bound estimate of the mean, at a prescribed confidence level, used to represent the mean of the distribution, and some multiple of the standard deviation (or standard error) is used to define the design allowable, namely,... 

Table V distributes U.S. shipments of industrial finishes into eight end-use areas for 1980-82, with projections to 1987. Declines in gallonage are indicated in markets for metal, wood, and transportation finishes. However, some of this is due to the projected greater use of high-solids (HS) finishes overall, consumption of IF by dry gallon is expected to be about the same from 1982 to 1987, since the average nonvolatile content by volume is expected to increase from 40% to about 50%. Can coatings will be affected by state returnable-container laws, the upsurge in the use of glass bottles, and the growth of plastic containers for soft drinks.
