Comparative data horizontal

Comparative data on three types of scrubbers used in supeiphosphate plants are presented by Pettit (1951 A, B). Although no conclusions are drawn in the study, the data, which are summarized in Table 6-16, indicate that the horizontal scrubber offered the highest efficiency with the lowest water-flow rate. The high efficiency of this unit probably resulted from the use of high-pressure nozzles and the long tortuous path which the gas stream was forced to follow. 

For horizontal surfaces facing upward, coefficient K should be increased by 30%, and for horizontal surfaces facing downward, it should be decreased by 30%, compared with the data from Table 7.5. ...

The profile shown in Figure 43.17 illustrates two different data acquisition points, one measured vertically and one measured horizontally, on the same machine and taken at the same time. Because they were obtained concurrently, they can be compared to determine the operating dynamics of the machine. 

In Fig. 2.9 the theory is compared with some experimental data. In these coordinates the Hubbard relation corresponds to a horizontal straight line with intercept 1/6, but for any finite xj deviations from 1/6 are observed. The angle formed by the straight lines with y=0 and y= defines the acceptable range of slopes. If experimental points are within the angle, the impact description may turn out to be acceptable. The above method for testing experimental data is considerably different from the conventional one. As a rule, the Hubbard relation is checked... 

Figure 11. Comparative potencies of several saxitoxins and tetrodotoxin in the mouse bioassay, displacement of radiolabelled saxitoxin from rabbit brain, and block of single batrachotoxin-treated rat sarcolemmal sodium channels incorporated into planar lipid bilayers. The horizontal axis is the log of the potency relative to saxitoxin. Compound numbering corresponds to that in Figure 1. Data from Ref. 10, 94, 95.

As expected, the estimated values were found to be closer to the correct ones compared with the estimated values when the water-oil ratios are only matched. In the 2nd run, the horizontal permeabilities of layers 5 to 10 (6 zones) were estimated using the value of 200 md as initial guess. It was found necessary to use the pseudo-inverse option in this case to ensure convergence of the computations. The initial and converged profiles generated by the model are compared to the observed data in Figures 18.25a and 18.25b. 

The constants CrC6 and FrL for each fluid are evaluated from the experimental data. The correlation thus obtained compared reasonably well with experimental data (Wright, 1961 Jallouk, 1974 Shah, 1976, 1982 Steiner and Schlunder, 1977 Gungor and Winterton, 1986). In a later article, Kandlikar (1989) simplified the above equations into one for both vertical and horizontal tubes ... 

The separated flow models consider that each phase occupies a specified fraction of the flow cross section and account for possible differences in the phase velocities (i.e., slip). There are a variety of such models in the literature, and many of these have been compared against data for various horizontal flow regimes by Duckler et al. (1964a), and later by Ferguson and Spedding (1995). 

Model results in seawater are in good agreement with observational data of PFOA. Most differences can be attpageributed to deficiencies of the emission scenario. Despite this fact, the difference between model results and observational data are due to the limited horizontal and process resolution and the fact that the physical parameters of the model (temperature, surface pressure, vorticity or divergence of the wind velocity field) were not relaxed to observational data. Regarding these limitations, in particular individual vertical profiles compare quite well with observations. This study underlines the importance of the ocean as a transport medium of PFOA. The contribution of volatile precursor substances to long-range transport needs to be assessed. 

TSR 15). The data (Tables IV-VI) suggest that this instrument provides a satisfactory method for measuring heat release, even in the horizontal mode. Furthermore, it can differentiate between those materials which are prone to release much heat rapidly and those which perform much better in terms of heat release. The reliability of smoke data is, in principle, lower than that of heat data. In order to establish some criteria, the Tables include SmkFct values at 5 min (in MW/m2), which will be compared with SmkFct and SmkPar values for the same materials tested in the Cone and with values of specific maximum smoke density measured in the NBS smoke chamber. 

Data belonging to distribution profiles may be compared either vertically along the release/response ordinate or horizontally along the time abscissa. The semi-invariants (moments) provide a complete set of metrics, representing both aspects in logical sequence AUC accounts (vertically) for the difference of the extent, the mean compares (horizontally) the rates, and higher-order moments and higher-order statistics (variance, etc.) characterize the shape aspect from coarse to finer. 

Figure 7. A Mg vs. 5 Mg plot of calcite speleothems and their drip waters from the Soreq cave site, Israel (data from Galy et al. 2002) compared with seawater. The horizontal trend of the data suggests that Mg in carbonates is related to aqueous Mg by equilibrium fractionation processes. Results of a three-isotope regression, shown on the figure and in Table 3, confirm that the (3 value defined by the data is similar to the predicted equilibrium value of 0.521 and distinct from kinetic values. The positive A Mg characteristic of the speleothem carbonates is apparently inherited from the waters. The positive A Mg values of the waters appear to be produced by kinetic fractionation relative to primitive terrestrial Mg reservoirs (the origin).

Figure 8. A Mg vs. 5 Mg plot of limestone, dolostone, and marble samples (data from Galy et al. 2002) compared with a sample of foraminifera of various species (Chang et al. 2003) and seawater (Chang et al. 2003, this study). The broadly horizontal trend of the carbonates at elevated A Mg suggests a component of equilibrium fractionation relative to seawater. The P value derived by regression of these 5 Mg and 5 Mg data is within the range for equilibrium fractionation and statistically distinguishable from purely kinetic fractionation.

Table 6-3 shows 1 jr values calculated from the data in Table 6-2. The data in each vertical column show the monomer reactivities of a series of different monomers toward the same reference polymer radical. Thus the first column shows the reactivities of the monomers toward the butadiene radical, the second column shows the monomer reactivities toward the styrene radical, and so on. It is important to note that the data in each horizontal row in Table 6-3 cannot be compared the data can be compared only in each vertical column.

Both horizontal and vertical plates were used by Jakob and Linke (J4) for nucleate boiling of water at low heat fluxes. The results were nearly identical for these two cases. No other data are available for comparing orientation of plates. 

Use the same series of data and follow the same procedure as before to try out the four Traficante window types. Use the Interactive option, as a starting value set LB = 0, which yields a horizontal line and corresponds to no weighting. Increase and decrease the LB value in small steps using the scroll bar and try to predict the effect on your spectrum. Use different values to enhance the resolution, store the results and compare the resulting spectra using the multiple display. 

With J-Resolved spectra a further option for symmetrization is available (Symj), which compares the values (y-amplitudes) of pairs of data points situated symmetrically on opposite sides of the horizontal line through the centre of the data matrix. Again the two modes as discussed above can be selected. However in this case, the Tilt operation (section 5.4.3.2) must first be applied prior to symmetrization. 

Labuntsov (L2), 1957 Heat transfer to condensate films on vertical and horizontal surfaces. In laminar region, Nusselt equations are corrected for (a) inertia effects, (b) variation of physical properties with temperature, (c) effects of waves. In turbulent region various universal velocity profiles are used. Results compared with experimental data.
