Development And Preliminary Application Of Mathematical Models To The Weber Basin, W. J. Grenney, D. S. Bowles, M. D. Chambers, J. P. Riley Dec 1974

Development And Preliminary Application Of Mathematical Models To The Weber Basin, W. J. Grenney, D. S. Bowles, M. D. Chambers, J. P. Riley

Reports

The adoption of stream standards, whether for direct application or for the establishment of realistic effluent standards, creates a need to predict the impact of pollution loads on river water quality during critical flow periods or as the result of future user demands. Because of the complexity of aquatic systems, mathematical models are an excellent medium for bringing together the state-of-the-art knowledge from a variety of disciplines into a form which can be readily applied to practical problems. Applying a mathematical model to a river system has the added advantage of providing a structure for the systematic consideration of the …


Multiple Uses Of Utah Irrigation Canals: Cache County As A Case Study, James J. Kennedy, Komain Unhanand Dec 1974

Multiple Uses Of Utah Irrigation Canals: Cache County As A Case Study, James J. Kennedy, Komain Unhanand

Reports

Irrigation use is an obvious benefit of Utah canals that has been recognized for over 100 years. This study attempts to illustrate other, less obvious, uses. the major use examined was recreational, but canals are presently functioning as storm drainage systems and have potential for diverting flood crests in many river systems.

Recreational use of canals falls into two categories. There is passive use such as its landscape values, affects on creating shade and bird-wildlife habitat, etc., that is difficult to quantify but no less important than active canal use such as tubing, hiking, bank-play, bicycling, etc. We selected several …

Water Salvage Potentials In Utah, Volume I. Open Water Evaporation And Monolayer Suppression Potential, Trevor C. Hughes, E. Arlo Richardson, James A. Franckiewicz

Reports

An estimate of the potential in Utah for evaporation suppression by the monolayer film method is presented. The model estimates evaporation suppression as a function of wind speed, a four parameter exposure factor, and reservoir size. The estimated suppression factors vary from 0 to 30 percent and average 11 percent of the statewide total annual evaporation. Estimates of May to October evaporation and suppression potential are calculated for each of the 227 impoundments in the surface water inventory. A forthcoming report in this series will examine the potential for evaporation suppression by thermal destratification. This procedure, which is already being …


An Evaluation Of In-Stream Structures Designed To Provide Fish Habitat, Charles H. Call Jr. May 1974

An Evaluation Of In-Stream Structures Designed To Provide Fish Habitat, Charles H. Call Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In-stream concrete structures were studied through model tests and river tests. The model studies indicated that four designs provided good habitat in the model stream. These structures were the inverted weir, the "V" structure, the slab with legs and the cylinder. Through the river studies it was determined that these structures did not influence enough of the total river area to be effective in providing good fish habitat. Also an appreciable amount of yearly maintenance would be required to free the structures from silting in, debris, and vandalism. The slab with legs was the only promising structure.

Prospects For Conversion Of Solar Energy Into Electrical Power, William R. Cherry Apr 1974

Prospects For Conversion Of Solar Energy Into Electrical Power, William R. Cherry

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

In 1972, the Solar Energy Panel took a broad look at solar energy across the whole field to see just what could be done with this energy source. Maybe the era of acquiring energy without regard to cost and without regard to consequences of using it is beginning to come to a close and maybe we ought to start looking at the newer sources of energy, even though we need every bit of energy we can get from every source. I am not trying to say we don't need gas, oil, coal and nuclear energy. We are not going to …


The U. S. Wind Power Program, Joseph M. Savino Apr 1974

The U. S. Wind Power Program, Joseph M. Savino

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Today I would like to talk about wind energy in, basically, two parts. I would like to bring to your attention some of the developments that have occurred in the 20th century. Many of us who have gone through school in the last 25-30 years don't recall anywhere in our engineering education much information dealing with wind energy, and that may come as a surprise to you as it did to me, to learn how much has actually been done in the 20th century to develop large scale wind-driven machines. After I get through with that introduction I would like …

Attention is focussed upon the unique qualities of high energy fission particles, and upon the fundamental limits to the direct removal of their kinetic energy by electrostatic means and by cyclotron resonance deceleration. Efficiencies of secondary and tertiary product ionization and excitation produced by fission particles are examined. The potential for delivery of power through various non-thermal modes is discussed, and the significant unknowns relating thereto are identified.


Locating Nuclear Power Plants Underground, Frank M. Scott Apr 1974

Locating Nuclear Power Plants Underground, Frank M. Scott

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

This paper reviews some of the questions that have been asked by experts and others as to why nuclear power plants are not located or placed underground. While the safeguards and present designs make such installations unnecessary, there are some definite advantages that warrant the additional cost involved. First of all, such an arrangement does satisfy the psychological concern of a number of people and, in so doing, might gain the acceptance of the public so that such plants could be constructed in urban areas of load centers. The results of these studies are presented and some of the requirements …

Are Nuclear Shipments Really Safe?, William A. Brobst Apr 1974

Are Nuclear Shipments Really Safe?, William A. Brobst

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

The transportation of nuclear materials is on the increase. Although nuclear shipments are only a very small fraction of the Nation’s hazardous materials shipments, they attract a great deal of public attention. Shipments of spent nuclear fuel and nuclear wastes are a particular concern.

One of the many fears that people have about nuclear energy is the possibility that a nuclear shipment might somehow go awry and cause a serious public hazard. Primarily, they are worried that a shipment of spent reactor fuel or highly radioactive waste could be involved in a serious rail or highway accident and dump its …


The Energy Problem -- Crude Oil, J. A. Marshall Apr 1974

The Energy Problem -- Crude Oil, J. A. Marshall

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

This paper discusses the national energy problem as it affects the demand for and availability of crude oil. Forecasts of energy demands to 1990 have been made based on population trends and changing life styles in the USA. Projections of energy supplies show a rapidly increasing gap between supply of crude oil and demand for crude oil from the early 1970's through 1990. The need for imported crude oil to supply the forecast deficit is discussed. The political and economic implications of these imports are also discussed. The need for refineries, port facilities, tankers, and pipelines are presented. Finally, recommendations …

The amount of solar energy collected is stored in a combination of hot air and hot water storage system located underneath the house. An auxiliary electric heating coil is built into the solar heating system for use in any extended period of cloudy and inclement weather. The system is so designed as to satisfy the two key requirements for any successful solar …


The Role Of Natural Gas And Lng In Supplying Our Energy Needs, D. L. Caldwell Apr 1974

The Role Of Natural Gas And Lng In Supplying Our Energy Needs, D. L. Caldwell

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

The domestic natural gas industry experienced a spectacular growth during the two decades from 1950 to 1970. Demand for gas continues to rise and production has peaked at a time when the price for other energy sources is escalating. A price increase can stimulate production over the short term. Massive LNG imports can help the intermediate term supply. The long term natural gas situation is bleak and substitute natural gas sources must be employed. A conservation program and reordering of priorities for energy sources is essential for the United States as well as most industrial nations.


Oil Shale And Its Potential Utilization, G. U. Dineen Apr 1974

Oil Shale And Its Potential Utilization, G. U. Dineen

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

The large deposits of oil shale in the Green River Formation in Colorado, Utah, and Wyoming offer a potential source of significant quantities of liquid fuels. This paper discusses the location and potential of the resource; the present state of technology for producing shale oil by both aboveground and in situ processes; the characteristics of shale oil; environmental aspects of oil-shale utilization; and recent developments, particularly results of the Department of the Interior’s Prototype Oil Shale Leasing Program, that suggest inauguration of commercial oil-shale processing.


Energy From Biochemical Sources, G. J. Fennewald, D. L. Million, Efton Park, J. L. Gaddy Apr 1974

Energy From Biochemical Sources, G. J. Fennewald, D. L. Million, Efton Park, J. L. Gaddy

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

As available energy reserves decline, renewable sources must be utilized. Organic matter, grown agriculturally, represents a renewable energy source, which is readily available. This paper reviews the methods by which organic matter can be converted to energy sources by biochemical processes. The economics of conversion of agricultural crops and byproducts to alcohols by fermentation and conversion of these agricultural materials to methane by anaerobic digestion are examined. Projections of the potential of this energy source are quite promising.


Coal And Its Derivatives As An Energy Resource, W. G. Stockton Apr 1974

Coal And Its Derivatives As An Energy Resource, W. G. Stockton

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

April 25, 1974

Events of the last few months, it seems, have somewhat altered the public countenance of the coal industry. These events, I am sure, are the generating factors focusing interest on our industry currently, and I suspect they account for my invitation to address this distinguished group of engineering students today on the subject of coal in this nation's energy outlook.

Coal Mining is not a new industry - - it has been around a long, long time. A surprising number of people, though, have never seen any coal; they are not aware of the existence of the …


Hydrogen -- An Emerging Energy Carrier, James E. Funk Apr 1974

Hydrogen -- An Emerging Energy Carrier, James E. Funk

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

The "hydrogen economy" envisions the energy needs of the United States in the early part of the next century being served by a network of nuclear plants producing electricity, hydrogen, and perhaps desalted water. Hydrogen is a very attractive synthetic fuel and offers appealing features as an energy carrier. This paper considers a number of factors involved in the expanded use of hydrogen including supply and demand, production techniques and transmission and storage.


Status And Outlook For Energy Conversion Via Fuel Cells, John P. Ackerman Apr 1974

Status And Outlook For Energy Conversion Via Fuel Cells, John P. Ackerman

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Fuel cells have the potential of providing good solutions to a variety of energy-related problems. As our supplies of conventional fossil fuels are depleted, their cost will rise, and there will be increasing difficulty in obtaining certain premium fuels at any price. It behooves us, then, to use our remaining reserves of fuels as efficiently as possible. Energy conversion via fuel cells represents one of the best ways to achieve this goal, because it is possible, simultaneously, to obtain more work and less pollution from a dollar's worth of fuel with a fuel cell than with any other device.


Energy Saving Projects Recently Completed At A Large Petroleum Refinery, J. A. Marshall, A. D. Kiehne Apr 1974

Energy Saving Projects Recently Completed At A Large Petroleum Refinery, J. A. Marshall, A. D. Kiehne

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

A significant reduction in energy consumption per barrel of crude oil processed has been effected at Shell Oil's Wood River, Illinois, Refinery during the past two years. Some of the projects which have resulted in reduced energy consumption are:

1. Improved furnace efficiency through closer surveillance and through installation of optimizing controllers on certain furnaces.

2. Lowered reflux-to-feed ratios on certain fractionating columns following reoptimization of operating conditions with current fuel values.

3. Additional heat exchangers purchased and installed on plants originally designed and optimized at lower fuel values.

This paper discusses examples of each of the above projects and …


An Overview Of Natural Gas Supply And Availability, D. E. Gibbs Apr 1974

An Overview Of Natural Gas Supply And Availability, D. E. Gibbs

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Natural gas presently supplies almost one-third of the total U.S. energy supply--and like oil, has had its proven reserves reduced by ever-increasing production. The potential gas reserves of the United States are sufficient to maintain our present demand for a considerable period of time, if these reserves can be found. The exploration necessary has to be financed by increased gas cost. Additional technology will be necessary to increase the amounts of gas that can be produced from our present and future supplies. Several methods of obtaining the capital necessary to perform the additional drilling and areas of technical improvement are …


Bellamy Field Tests: Recovery Of Medium Gravity Crude Oil From Missouri Tar Sands By Counterflow Underground Burning, J. C. Trantham Apr 1974

Bellamy Field Tests: Recovery Of Medium Gravity Crude Oil From Missouri Tar Sands By Counterflow Underground Burning, J. C. Trantham

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

In the current energy shortage, the heavy oil and tar sands of the United States are assuming critical importance. This is true for at least two reasons: first, they constitute a major resource, amounting to some 150 billion barrels in place; and second, their where-abouts is known -- exploration will not contribute to the lead time required for bringing these resources into the national energy picture. Moreover, many of the technological problems have been solved. The delay in producing these heavy oil and tar deposits is due primarily to economics.

This paper describes Associated's energy control system as it was originally installed, as it is currently operating today, and as it is currently envisioned to …


Energy And The Environment, Joseph T. Zung Apr 1974

Energy And The Environment, Joseph T. Zung

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

The topic of Energy and Environment is probably the most timely one at present time. Probably it is not because both energy and environment are man's most precious resources we want to conserve, but because of their seemingly contradictory and mutually destructive nature. One often asks ourselves these days: Is the energy crisis an environmental problem or environmental restrictions caused our present energy crisis?


A Technique For Improving Stability Of Petroleum Reservoir Simulation Models, M. D. Arnold, T. C. Wilson, A. Herbert Harvey Apr 1974

A Technique For Improving Stability Of Petroleum Reservoir Simulation Models, M. D. Arnold, T. C. Wilson, A. Herbert Harvey

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Computational instability may occur in the mathematical simulation of hydrocarbon reservoirs when small inaccuracies in the calculated pressures cause loss of diagonal dominance in the matrix of coefficients. The problem can be resolved by the use of a more precise technique for computation of pressures. However, this stability problem is still troublesome to users of certain types of reservoir simulators. A computational technique which has been found effective in resolving the problem is presented.
