An Investigation Of Methods For Reuse Of Rubber Tires, Charles Edward Armbruster
An Investigation Of Methods For Reuse Of Rubber Tires, Charles Edward Armbruster
Retrospective Theses and Dissertations
Methods of reusing/recycling the more than 250 million automobile and truck tires which are worn out each year were investigated. The existing methods of reusing tires account for about 30 percent of the volume of scrap tires generated each year. These methods are, Retreading, Reclaiming (by reducing to ground up rubber and fiber), and Tire Splitting (stamp items out of sidewall and tread areas). Several possibilities for reusing/recycling the unused 70 percent were discovered. These methods are as follows: Destructive Distillation -- a method of recovering chemicals from tires by pyrolitic action. It is anticipated that eventually as much as …

A Mathematical Model For Determining The Thermal Distribution Resulting From Discharge Of A Heated Effluent, Alan H. Epstein
A Mathematical Model For Determining The Thermal Distribution Resulting From Discharge Of A Heated Effluent, Alan H. Epstein
Retrospective Theses and Dissertations
A mathematical model is presented for the problem of determining the two-dimensional temperature distribution resulting from the discharge of a heated effluent into a shallow, quiescent receptacle. The physical model of the problem is the two-dimensional jet augmented by an imposed condition of viscous drag due to bottom friction effects. By virtue of the assumption that the physical properties of the effluent are independent of temperature over the operational temperature range of the plume, the analysis separates the total problem into a flow problem and a temperature problem. Solution of the temperature distribution is accomplished both analytically and numerically. Analytically, …

Computer Method For Airport Noise Exposure Forecast, John Michael Bateman
Computer Method For Airport Noise Exposure Forecast, John Michael Bateman
Retrospective Theses and Dissertations
The major problem facing air transportation for the next decade is aircraft noise. The noise level due to the operation of large jet aircraft has created a very serious annoyance problem to the people living near of adjacent to jet airports. The noise problem has developed both for take-off and landing operations of these aircraft with take -off noise causing the greatest annoyance factor. A technique called Noise Exposure Forecast (NEF) has been developed to identify the annoyance factor of these noises to people and activities on the ground. With these NEF ratings or numbers, planners can better determine the …

Localized Wastewater Treatment Facilities, Robert Russell Garrett
Localized Wastewater Treatment Facilities, Robert Russell Garrett
Retrospective Theses and Dissertations
The report describes an alternative to the use of septic tanks for invidual dwellings. The major problems confronting the larger wastewater treatment plants (0.012 to 10 million gallons per day) in central Florida are also discussed. Solutions in this report are for individual and multi-unit dwelling treatment systems (to 0.06 MGD). these units can provide 90% biochemical oxygen demand (BOD) and suspended solids (SS) removal in accord with new state and county regulations. A comparison of the large versus the small plants reveals that small innovative plants, though more expensive, are more environmentally sound than the poorly operated large facilities. …

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 …

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 …

Water Resources Planning To Satisfy Growing Demand In An Urbanizing Agricultural Region, Thomas C. Anderson
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 …
Studies To Develop And Investigate An Inverse Formulation For Numerically Solving Three-Dimensional Free Surface Potential Fluid Flows, Roland W. Jeppson
Studies To Develop And Investigate An Inverse Formulation For Numerically Solving Three-Dimensional Free Surface Potential Fluid Flows, Roland W. Jeppson
Reports
An inverse formulation is developed for solving three-dimensional potential fluid flows which considers the magnitudes of the cartesian coordinates x, y, and z as the dependent variables in the space defined by the potential function and two mutually orthogonal stream surface functions whose intersection defines the physical space streamlines. This formulation reverses the usual role of the variables. In this inverse space irregular boundaries, with unknown position in the physical space, such as free surfaces become plane boundaries, and the space of most potential flow problems is a parallelepiped. The basin partial differential equations resulting from this formulation are nonlinear …
The Hydraulics Of Waste Stabilization Ponds, Gary Z. Watters
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 …
