Sedimentary Framework of the Modern Mississippi Delta

Abstract: The arrangement of sedimentary traits in the birdfoot delta of the Mississippi River is comparable to the structure of a leaf. Present-day facies can be correlated with delta platform deposits obtained from borings. The shape and distribution of sedimentary units, as disclosed from these borings, are shown on maps and sections. Factors controlling delta growth are the load of the river, number of main distributaries of the river, depth of water into which the delta front advances, and subsidence. The rate of lengthening of Southwest Pass, as determined from hydrographic surveys, provides a basis for establishing the rate of bird-foot delta growth and the date when the delta started to form, approaximately 1500 A.D. Since then, nearly 27 cubic miles of sediment have accumulated in the elta platform.

Two‐phase concurrent flow in packed beds

Abstract: Pressure drop and liquid saturation accompanying two-phase concurrent flow have been studied in a variety of packings and with gas-liquid systems having a wide range of fluid properties. Two basic flow patterns were observed with nonfoaming systems. Correlations of pressuredrop and liquid-saturation data were obtained in terms of the single-phase friction losses for the liquid and the gas when each flows alone in the bed. Deviations from the correlation with foaming systems are discussed and illustrated with sample data.

Numerical solution of two‐dimensional heat‐flow problems

Abstract: Two-dimensional heat flow frequently leads to problems not amenable to the methods of classical mathematical physics; thus, procedures for obtaining approximate solutions are desirable. A recently introduced finite-difference method, known to be applicable to problems in a rectangular region and involving much less calculation than previous methods, is extended by example to cases of more practical interest. Although all three examples given are steady state, unsteady state problems may also be attacked successfully by the method. The first example is that of flow around a corner and indicates that a more complicated region than a rectangle can be treated. Then a problem involving a radiation-boundray condition is given; as this condition is nonlinear, the method is extended to more general equations. The last example involves point heat sources and sinks in an elliptical region and so extends the method to treat curved boundaries (as distinguished from polygonal domains) and singular points. It is believed that materially less calculation is necessary by this method than for previous procedures.

Corrosion Inhibition in HCl Using Methyl Pyridines

Abstract: The inhibiting effect of pyridine and seven of its methyl derivatives on the corrosion of iron in O2‐free, at 35°C was determined. Corrosion rates were measured by colorimetric analysis for iron with mercaptoacetic acid. The relative inhibitor efficiency and cathodic potential shift increased with increasing inhibitor concentration and, for a given concentration, with increasing electron density at the nitrogen atom. Both increased slightly with decreasing concentration, but a temperature increase of 10°C had no effect on either. The proposition that chemisorption is involved in corrosion inhibition is supported by these experiments. As a supplementary item the great importance of careful purification of the organic compounds used in such researches as this is documented.
