  • Pressure distribution around a circular cylinder resting on a flat boundary in an oscillating fluid

    Creator:
    Johnson, Ronald Ernest
    Abstract:
    This study was undertaken to provide information needed in the design of ocean outfalls. A review of past investigations concerning forces on submerged objects is presented. Objects independent of any boundary and cylinders in boundary contact are considered. A solution for pressure distribution about a circular cylinder resting on a...

  • Jet diffusion as related to ocean outfall systems

    Creator:
    Buford, Gary Manford
    Abstract:
    This study discusses important aspects of the ocean which should be considered in the design of a sewage outfall system; conditions are restricted to those of the Oregon coastal area. They include predominant currents, upwelling tendencies and ocean bottom characteristics. Major emphasis is placed upon investigation of diffusion characteristics of...

  • Alum coagulation in conjunction with the activated sludge treatment of corn processing waste water

    Creator:
    Jensen, Harold LeRoy, III
    Abstract:
    The treatment of waste water from a corn freezing process by activated sludge with the aid of alum coagulation was investigated. Both high and low energy level systems were observed with good flocculation occurring at the low energy level. Because poor flocculation occurs at high energy level conditions, alum was...

  • Web buckling failure of built-up girders with rectangular holes

    Creator:
    Cato, Stuart Leslie
    Abstract:
    This thesis investigated the methods of failure in the webs of built up girders. The beams had rectangular holes five and one-half inches wide and seven and one-half inches high with rounded corners in a web fourteen inches deep between flanges. The longitudinal position of the hole edge varied from...

  • The effect of elevated pressure and high shear on oxygen uptake rates in activated sludge

    Creator:
    Streebin, Leale E.
    Abstract:
    The purification capacity of an activated sludge process is highly dependent of the rate of oxygen transfer from the air to the microorganisms. This rate can be increased in an air diffusion system by subjecting the culture to high shear and high pressure. A study of the effects of high...

  • Removal of dieldrin from water by granular-activated carbon

    Creator:
    Hardman, Michael Harvey
    Abstract:
    A 9.0 ppb solution of dieldrin in water was passed through a granular-activated carbon bed at the rate of 4 gpm/sq. ft. The performance of the carbon was monitored from sampling ports at bed depths of 2-1/4 and 8-1/4 inches. Isotherm tests were also run with a 9.0 ppb dieldrin...

  • The effect of surface configuration on evaporation from a porous stream model

    Creator:
    Tichenor, Bruce A., 1940-
    Abstract:
    A stream's temperature is a major factor in its ability to support fish life and to be utilized for other beneficial purposes. The approach most generally used for stream temperature prediction is the Energy-Budget method, which involves the inventory of all the energy entering and leaving the stream. A temperature...

  • The present status of plastics as an engineering material

    Creator:
    Summersett, John Steve
    Abstract:
    The present status of plastics is one of constant change, but this thesis attempts to focus attention on the state of the industry as of 1967. Beginning with a brief title definition and history of plastics, the writer proceeds to a discussion on the structural characteristics of plastics. Under this...

  • The evaluation of the field vane shear strength analysis of the Glen Aiken creek embankment failure

    Creator:
    Clarke, James Dennis
    Abstract:
    A post-failure investigation of a highway embankment constructed over organic and sensitive subsoils was made with a series of field vane tests. The results indicated that the embankment was quite stable, and, therefore, the reliabilities of both the Φ = 0 slip-circle analysis and the field vane results seemed to...
