Experimental density

The term essentially a drag coefficient for the dust cake particles, should be a function of the median particle size and particle size distribution, the particle shape, and the packing density. Experimental data are the only reflable source for predicting cake resistance to flow. Bag filters are often selected for some desired maximum pressure drop (500—1750 Pa = 3.75-13 mm Hg) and the cleaning interval is then set to limit pressure drop to a chosen maximum value. 

Fig. 6.8. The dependence of rj2 on x) by the Ivanov model (I) and friction model (F) in comparison with predictions of the extended. /-diffusion (ED) and Langevin (L) models for linear molecules. The line (H) corresponds to the Hubbard inverse proportionality between xgj and xj at very high densities. Experimental data from [81] are in rectangles around line G with the length of their vertical and horizontal sides being equal, correspondingly, to the experimental errors in x el and rj measurements. Experimental data from [270] (J) are shown both in original position and shifted down by a factor of four (broken line).

Experimental data, normalized to the resistance 9ts of the saturated membrane at various temperatures have been extracted from Ref. 94. They are compared to the values calculated in the hydraulic permeation model (main figure) and to the results of the diffusion model, taken from Ref. 7 (inset).

Pure polymer densities Experimental data for a number of polymers are correlated via the Tail equation and are summarized in the DIPPR Polymer Project. Recently, an extensive compilation of polymer densities (using the Tait equation) has been presented by Rodgers. The Tait equation is a five-parameter correlation of the density of polymers as a function of both temperature and pressure. It provides an excellent correlation over extended temperature and pressure ranges. 

The heat capacity obtained from Equation 46 increases monotonically with the density. Experimentally it is known that at high densities the heat capacity decreases with increasing density.
