Analysis Of Time-Independent Consolidation Data, E. Gregory Mcnulty, Tommy C. Hopkins, C. Thomas Gorman
Analysis Of Time-Independent Consolidation Data, E. Gregory Mcnulty, Tommy C. Hopkins, C. Thomas Gorman
Kentucky Transportation Center Research Report
The one-dimensional laboratory consolidation test developed by Terzaghi permits deformation and drainage only in the vertical direction. The stress-strain characteristics of data obtained from this test are normally studied using a semilogarithmic graphical representation, that is, vertical strain or void ratio is plotted as a function of the logarithm of effective stress. Such a representation permits an analysis of the stress history and compressibility characteristics of soils. Knowledge of these material characteristics is of great practical value in the prediction of settlement associated with loading where the effects of lateral consolidation may be neglected.

Predicted And Measured Drainable Porosities For Field Soils, R. W. Skaggs, Larry G. Wells, S. R. Ghate
Biosystems and Agricultural Engineering Faculty Publications
Experiments were conducted on large field cores to determine the relationship between drainage volume and water table depth for five soils. The measured drainage volumes were less than predicted from the soil water characteristics for three soils, but were in good agreement for the other two. Drainable porosities were calculated from both theoretical and experimental drainage volume-water table depth relationships by assuming that the unsaturated zone is essentially 'drained to equilibrium, with the water table. The experimental drainable porosities thus obtained were less than predicted.
Drainable porosities for drainage in two-dimensions were calculated from experimental results for one-dimension by assuming …

The Effects Of Interstage Backmixing On The Design Of A Multicomponent Distillation Column, Gary D. Loud, Raymond C. Waggoner
The Effects Of Interstage Backmixing On The Design Of A Multicomponent Distillation Column, Gary D. Loud, Raymond C. Waggoner
Chemical and Biochemical Engineering Faculty Research & Creative Works
Interstage back mixing is encountered as entrainment in many distillation columns. Bidirectional back mixing is common in liquid-liquid extraction. These effects, which reduce the effectiveness of a separation process, may interfere with its operation even to the extent of shutdown. The design engineer and process operator need to recognize the effects of back mixing and must quantify them to take effective countermeasures. A procedure is developed which describes the effects of interstage bidirectional back mixing in multistage separations. It is implemented on an existing simulation for multicomponent distillation and is used to show the effect of back mixing on product …

Sld Potamology Study (S-9), Jerome A. Westphal, Samuel P. Clemence
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
Foreword
In this report, the authors discuss factors which relate to flow characteristics of the Middle Mississippi River and its major tributaries. The variety of ways in which man and nature interact to affect the hydrologic regime of the study area are almost infinite. Furthermore, the intensity and direction of man's activity is non-uniform with respect to both time and space. Therefore, on the scale of the study area, the authors assert that 1) it is difficult to verify associations between specific human actions and river responses and 2) at this time, it is impossible to do so in a …

Disk And Strip Forging With Side Surface Foldower: Part 2: Evaluation Of The Upper-Bound Solutions, Ronald A. Kohser, B. Avitzur
Materials Science and Engineering Faculty Research & Creative Works
The upper-bound solutions developed in Part 1 are evaluated with regard to their ability to produce a lower value for required power (load, pressure, or work). Comparisons made with existing solutions such as the triangular field solution and one-zone bulge solution show that for strip, each solution has a domain of geometry and friction in which it is superior. The new solution produces a lower upper-bound for conditions of high interface, friction and relatively thin specimen, the area where fold over is the observed mode of flow. For solid cylindrical disks, the solution fails to improve upon existing analyses, but …

Engineering Properties And Slope Stability Settlement Analysis Related To Phosphate Mine Spoil Dumps In Southeastern Idaho, Richard E. Riker, Loren R. Anderson, Roland W. Jeppson
Reports
The engineering properties of waste spoil from phosphate mines in Southeastern Idaho were determined through field and laboratory testing. Based on these properties, the slope stability and settlement characteristics of phosphate spoil dumps were determined. Hypothetical examples illustrate possible modes of foundation failures. Such failures might occur when weak foundation soils exist of when there is a lack of embankment-foundation preparation prior to the disposal of waste material. Adequate protection against slope failure occurring through the embankment material can be accomplished by grading embankment finish slopes to 2 ½ horizontal to 1 vertical or flatter and taking proper caution to …

Economic Impacts Of Two Proposed Power Plants On Utah's Irrigated Agriculture, Rangesan Narayanan
Reports
Introduction: The impact on agriculture of a large coal-fired stream electic plant (such as the proposed Intermountain Power Project near Lynndyl, Utah) or a large nuclear electic plant (such as proposed for the Green River Site near Emery, Utah) depends on a large number of factors. Among the most important are the technology used in power plant design, the site-characteristics of the plant location, the availability of water resources in the vicinity of the plant, the quality of the available water, and the types of agricultural uses and their water requirements. Some of these factors can be defined by obtaining …
