The ratio of p JPmin be as high as 1.52 depending on the material. Consequently, when bulk densities are reported it is important to note whether the value was determined under loose or tapped conditions, along with the mean particle size. Most literature values report an average bulk density that is representative of the material most often handled. Loose solids may be broadly characterized according to their bulk densities ... 

FIG. 20 (a) Density profiles p(z) vs z for e = —2 and four average bulk densities (f> as indicated, (b) Surface excess vs density in the bulk for four choices of e. (c) Profiles for the diagonal components of the pressure tensor and of the total pressure for (p = l.O and e = —2. Insert in (c) shows the difference between P, and Px to show that isotropic behavior in the bulk of the film is nicely obtained, (d) Interfacial tension between the polymer film and the repulsive wall vs bulk density for all four choices of e. Curve is only a guide for the eye [18]. 

The tests that reflect physical properties of the catalyst are surface area, average bulk density, pore volume, and particle size distribution. 

Many of these products are appropriate for either machine or hand washing. Most of them are marketed as compact detergents and have an average bulk density of 0.4—0.5 kg/L. 

Given the following data, calculate the average bulk density for the substance.

Proposed maximum waste feed rate to cavern = 20,000 Ib/day Feed rate schedule = 6 days/week Average bulk density of waste = 30 Ib/ft ... 

Figure 6.3 GCEMC results for the disjoining pressure /(s ) [see Eq. (5.57)] for a typical polar (Stockmayer) fluid as a function of the wall separation (data have been obtained at T = 1.60, m — 2.0, and p = -19.30 corresponding to an average bulk density p 0.6). Also shown are corresponding results for an atomic LJ (12,6) fluid at the same temperature and bulk density.

For specimens formed by the method proposed, the unconfined yield stress is uniquely determined by its average bulk density, independent of the number of increments in which it is formed. 

However, as we now know, the bulk density bd is not a constant. In fact, the average bulk density in the bed is a function of the mass of the bed and therefore time, giving at this point the following equation for the conservation of mass ... 

TS-1 as a new commercial catalyst of ENI company was reported by Perego et al. (218) Polimeri Europa s Web site (operated by ENI) (114) gives more details, from the properties of TS-1 to its applications. The catalyst capacity that is being newly installed amounts to more than 100 t/yr. The commercial products come in the form of extrudates for use in fixed-bed reactors or as microspheres for use in slurry reactors. The average bulk density of the extrudates is 650 kg/m, and that of the microspheres is 600 kg/m. ... 

Where, Oy is vertical stress K is stress concentration coefficient y is average bulk density of overlying strata H is occurrence depth t is attenuation coefficient M is roof thickness y, is roof bulk density x is width of limit equilibrium. 

Pb = average bulk density of grinding media charge [t/m ]. 

In order to estimate the width required to achieve a desired capacity, knowledge of the average velocity and the average bulk density of the material is required. The bulk density in this case is not the aerated bulk density, as there is a further de-rating factor to account for this.
