A Study Of Frictional Drag Force Reduction On A Flat Plate By The Injection Of A Dilute Solution Of Guar Gum Into The Boundary Layer, Neil Henry Clay
A Study Of Frictional Drag Force Reduction On A Flat Plate By The Injection Of A Dilute Solution Of Guar Gum Into The Boundary Layer, Neil Henry Clay
Theses and Dissertations
The study of frictional drag force reduction has been the subject of much research for many years. One of the significant developments in the field of frictional drag force reduction has been the discovery of the effectiveness of dilute polymer solutions in reducing drag. By using dilute high-polymer solutions frictional drag forces in pipe flow have been reduced by as much as 70 per cent.
A Study Of Thermal Responses Of A Body Of Complex Geometry To A Moving Heat Source, J. Norman Smith
A Study Of Thermal Responses Of A Body Of Complex Geometry To A Moving Heat Source, J. Norman Smith
Theses and Dissertations
The effect of the fusion welding process upon the metals being welded is a matter of great interest and has been the subject of much investigation, both theoretical and experimental. The properties of metals are determined by the structure of their crystals (within limits for any given metal), and the crystalline structure is determined by heating and cooling rates. Thus the knowledge of temperatures, and heating and cooling rates, becomes the key to understanding these effects of heating. Since the greatest part of fusion welding is done using a gas torch or an electric arc, the necessary theoretical study is …
Model Study And Analysis Of The Flow Elements Of A Recirculation Mixing System, Albert Warren Berg
Model Study And Analysis Of The Flow Elements Of A Recirculation Mixing System, Albert Warren Berg
Theses and Dissertations
The term water clarifier as used in this text refers to a versatile water treatment unit which combines flocculation and coagulation, clarification and positive sludge removal in a single tank. Water clarifiers are very compact units which are being used in municipal and industrial water treatment for the removal of turbidity, algae, color, iron and silica; lime or lime-soda softening; magnesium precipitation; brine clarification; and waste water clarification with or without chemicals. Water clarifier units have found wide use in the sanitary field, providing high removals in the pre-treatment of sewage and in secondary sewage treatment through addition of coagulants.
The Design Of A One-Man Terramechanism, Brent Charles Fryer
The Design Of A One-Man Terramechanism, Brent Charles Fryer
Theses and Dissertations
With the rebirth of special warfare in the last few years, the role of the individual soldier and of squad-sized units has been re-emphasized. Most guerilla-type fighting has been, is presently, and will most likely continue occurring in remote areas of the world. The terrain encountered may be tropical grasslands and canopy areas, or rugged mountains, inland waterways, swamps, mud flats and rice paddies. Other adverse terrain conditions are frequently encountered and must be crossed to accomplish the mission of the unit.
Correlation Of Weldment Hardness Profiles In Steels With Jominy End-Quench Data, Deepak Panjabi
Correlation Of Weldment Hardness Profiles In Steels With Jominy End-Quench Data, Deepak Panjabi
Theses and Dissertations
Welding occupies an important place as a major metal fabricating process and steel is the backbone of many an industry. Therefore it is of paramount importance to know the effect of welding on steel.
The Development Of Turbulent Flow In The Inlet Region Of Smooth Pipe, Forrest C. Smith
The Development Of Turbulent Flow In The Inlet Region Of Smooth Pipe, Forrest C. Smith
Theses and Dissertations
Turbulent flows are encountered in nearly every case where fluid motion is involved. Turbulent flow in pipes is of great practical interest, and the problem of flow in the entry region is of special importance since the great majority of applications are in the realm of developing flow.
Geographical Characteristics Of Early Mormon Settlements, John Haws Baum
Geographical Characteristics Of Early Mormon Settlements, John Haws Baum
Theses and Dissertations
Considerable literature has been written about the Mormons and their settlement of the lands within the Great Basin; yet no one has produced a systematic study which analyzes the following geographical factors: What pattern of land occupancy was actually used by these early pioneers? Which physical characteristics determined the selection of a site for the Mormon village? What type of city survey pattern was instigated as towns were established along the eastern margin of the Great Basin? What was the relationship between the forts and the settlements in their lay-out patterns? As these questions were systematically analyzed new findings were …
