The Hydraulics Of Waste Stabilization Ponds, Gary Z. Watters

Reports

The treatment efficiency of waste stabilization ponds depends primarily on the biological factors of type of waste and organic loading. However, the biological activity in a pond is greatly influenced by the environmental conditions of temperature, wind, sunlight, and the hydraulic flow patterns. In the past little attention has been given to the hydraulic characteristics of waste stabilization ponds such as the gross flow patterns within stabilization ponds as affected by the shape of the pond or lagoon, the presence of dead spaces, and positioning of inlets and outlets and the degree of density stratification. These hydraulic flow characteristics will …

Optimizing Resistance Coefficients For Large Bed Element Streams, D. E. Overton, Harl E. Judd, C. W. Johnson

Reports

This is a report of a comparison of Darcy resistance coefficients calculafed for previously reported laboratory data and those calculated for large bed element streams. Large bed element (LBE) streams exist frequently in nature where rocks derived from valley walls or from channels cutting through ancient glacial or fluvial deposits are moved only under conditions of extreme flood. The height of bed elements is a significant part of the mean depth of flow. The stream gradients are high and are quite stable for all but the highest flows.

Development Of Regional Supply Functions And A Least-Cost Model For Allocating Water Resources In Utah: A Parametric Linear Programming Approach, Alton B. King, Jay C. Andersen, Calvin G. Clyde, Daniel H. Hoggan

Reports

The development and allocation of the water resourcse within a state require water planners to prepare plans far in advance of the actual time new facilities are required. It is not easy to identify and evaluate all the possible alternatives for providing water which incorporate broad objectives such as economic efficiency, social welfare, regional development, recreation benefits, and conservation of environment. Water resources development entails the modification of a natural hydrologic system to better meet man's needs. The interrelationships among elements of the hydrologic system to better meet man's needs. The interrelationships among elements of the hydrologic system are relatively …

Calibration Of Parshall Flumes With Non-Standard Entrance Transitions, Cheng-Lung Chen, Calvin G. Clyde, Min-Shoung Chu, Chi-Yuan Wei

Reports

The 9-ince and 18-inch Parshall flumes with the throat section installed level with the bottom of an incoming pipe were tested. The measured discharges for given flow depths (free flow) or differences in flow depths (submerged flow) were found to deviate quite significantly fromt he computed standard Parshall flume disharges at both low and high flow rates. New empirical formulats have been developed to take such deviations into account. It is noted that values of the coefficients and exponents contained in the new formulas depend on the throat size of the flume and the slope of the incoming pipe. Calibration …

Water Resources Planning To Satisfy Growing Demand In An Urbanizing Agricultural Region, Thomas C. Anderson

Reports

Although it is condeded that an adequate supply of water is essential to economic growth and development, what constitutes an "adequate" supply is often controversial and difficult to determine. The problem can be solved by applying basin economic concepts: determining the value of water be estimating its supply and demand. This report demonstrates one method for doing this. The theory of the demand for irrigation water and its empirical application are discussed. An example problem based on data from one of the sub-regions of the study area (the Jordan River Basin of Utah) is presented to illustrate the method. The …

Kinetic Analysis Of The Radiation Polymerization Of Methyl Methacrylate–Kaolin Clay Composites, J. J. Beeson, Kenneth G. Mayhan

Chemical and Biochemical Engineering Faculty Research & Creative Works

In the first of a two‐part series, a kinetic study has been made on the effects of gamma rays (60Co) in air and inert gas on the polymerization of a 50:50 weight‐mixture methyl methacrylate (MMA)–kaolin clay system. The effect of dose rate (7.35–24.9 rads/sec), temperature (25° to 75°C), and total dose on the percentage conversion of monomer to polymer was studied. The rate of formation of polymer at 25°C in the composite system was found to be faster when compared to a bulk MMA system at the same dose rate. This acceleration showed that the clay had a catalytic effect …

Grain Boundary Diffusion In Ionic Crystals, Kulwant Singh Sabharwal

Doctoral Dissertations

"The diffusion of ¹³¹I in single crystals and along the tilt grain boundaries of pure and calcium chloride doped (142±5 ppm) bicrystals of sodium chloride, grown by Czochralski technique, was investigated using a microtome sectioning technique. Results on bulk diffusion in pure NaCl agree well with the results of earlier investigators and are represented by the D=(504 cm²/sec)exp (-2.27 ev/kT). Enhanced diffusion of ¹³¹I is observed along the grain boundaries and the presence of the dopant lowers the grain boundary diffusivity over the entire temperature range of 430ºC - 570ºC studied in the present investigation. Thermal activation and electrical polarization …

An Exact Analysis Of Two-Dimensional Radiative Transfer In An Absorbing And Emitting Gray Medium, William F. Breig

Doctoral Dissertations

"The exact formulations for the radiative flux and the emissive power are presented for a two-dimensional, finite, planar, absorbing and emitting, gray medium in radiative equilibrium. Exact expressions are obtained for the medium subjected to the following types of boundary conditions: (1) cosine varying diffuse, (2) cosine varying collimated, (3) constant temperature strip, and (4) the strip illuminated by a uniform collimated flux. The solutions for the physically unrealistic cosine varying models are used to construct the solutions for the more practical finite strip models. The two-dimensional equations are reduced to one-dimensional equations by the method of separation of variables. …

The Use Of Shaped Explosive Charges To Investigate Permeability, Penetration, And Fracture Formation In Coal, Dolomite And Plexiglas, Calvin J. Konya

Doctoral Dissertations

"The concentration of methane gas which exists in the exhaust air from a coal mine is critical. It can be controlled by dilution of the gas with fresh air or by the regulation of the rate of methane emission into the mine workings. Degasification techniques which control the emission rate are currently being developed. The use of shaped charges to initiate fractures in coal and increase the gas flow rate was the object of this research. The three areas of investigation were: 1) permeability changes in coal models after fracturing with shaped charge jets, 2) fracture formation in coal and …
