A New Technique For The Solution Of Free Convection Mass Transfer Boundary Value Problems, James Lewis Putman

Theses

Free convection mass transfer in boundary layer flow due to density difference in an isothermal model was studied. Previous work was examined and a quasilinearization technique was chosen to linearize the system of nonlinear partial differential equations resulting from the boundary layer continuity, momentum, and diffusion equations. This system of linear ordinary differential equations was solved by a computer program utilizing an iterative Gauss Jordan matrix solution technique. Results are presented and the convergence rate of the variables is plotted for each variable as a function of the distance from the boundary layer.

Rheology Of Asbestos Filled Polystyrene, Richard Henry Young

Theses

A capillary rheometer was used to generate data showing the volumetric flow rate at various pressures for a polystyrene resin and for an asbestos filled polystyrene. Variables evaluated were per cent asbestos and temperature. These data were then used to calculate the maximum shear stress at the capillary wall and the corresponding maximum velocity gradient (shear rate) at the capillary wall. A rheological equation containing three constants was employed to relate the shear stress to the shear rate. In addition, a simple relationship was found between the values of two of the constants and the per cent asbestos. There is …

Thin Layer Ionophoresis Of Sugars, Joseph Gilbert Vrindten

Theses

In 1952, Consden and Stanier published a report on paper ionophoresis of sugars in which they showed experimentally an increase in mobility of sugars with increasing pH in borate buffers. The object of the experiments in this thesis was to determine if this finding was also true of thin layer plates, there being no published literature on similar experiments using thin layer ionophoresis.

Glass plates 20 cm. x 20 cm. were coated with a 300 micron layer of cellulose powder and dried at 105° C. for one hour. They were then stored in an airtight tin box until ready for …

Enthalpy Deviations For The System Methane - Carbon Dioxide, Fred S. Winter

Theses

Enthalpy deviations for the gaseous system, Methane and Carbon Dioxide were developed using the Redlich-Kwong equation of state. Values of enthalpy deviation were obtained at 0.0, 0.0852, 0.19912, 0.3583, 0.6685 and 1.0 weight fraction Methane, at temperatures of 100° F, 280° F and 460° F, at pressures between 200 and 10,000 PSIA.

A computer program in Fortran IV language was developed for solving the Redlich-Kwong equation in terms of the compressibility factor.

The Redlich-Kwong expression for enthalpy deviation, in combination with graphical methods was used to produce the results.

Varying Contrast Of Ektacolor Paper By Rehalogenation Techniques, James Esser

Theses

By using rehalogenation techniques with Kodak Ektacolor paper, contrasts of nearly twice that produced by CP-5 processing were obtained. A metol-hydroquinone developer was used to produce a silver image which was rehaligenated and then developed in CP-5 developer to produce the colored image. By adding a restrainer to the MQ developer and then increasing development times, it was possible to produce a range of contrasts. Only slight changes in contrast were obtained by varying the MQ concentration. pH and development times at normal restrainer content. By reducing the color redevelopment time it was possible to reduce the contrast slightly.

Reaction Of Boron Trichloride With Methoxyamine Hydrochloride, Stephen L. Douglass

Theses

Boron trichloride and methoxyamine hydrochloride were reacted in refluxing chlorobenzene and again in a refluxing mixture of chlorobenzene and chloroform. Procedures for handling and analyzing samples under anhydrous conditions are discussed. Evidence is given for the formation of B-trichloro-N-trimethoxyborazine in the chlorobenzene/chloroform system.

An Active Fet Receiver Front End Mixer, Kenneth Voyce

Theses

In many recent receiver designs, the front-end mixer determines the receiver's sensitivity and its susceptibility to distortion from large input signals. Two balanced FET mixers are developed for such an application; a common source configuration and a common gate configuration. Each exhibits a range of 110 dB between the available input power necessary for 10 dB((S+N))/N sensitivity and the available input power of a two-tone signal which causes intermodulation products down 40 dB from the desired signals. An expression for the conversion transconductance of a junction FET used as a mixer is first derived from the device transfer characteristic equation. …

The Reaction Products And The Kinetics Of The Reactions Between Hypochlorite Ions And Thiosulfate And Tetrathionate Ions, Thomas Dagon

Theses

The reaction products of the hypochlorite oxidation of both thiosulfate and tetrathionate solutions were determined. In addition, preliminary kinetic studies were made dealing with the alkaline chlorination of thiosulfate solutions and with the hypochlorination of tetrathionate solutions. In the latter case, a pH dependent induction period was observed.

Experimental Investigation Of Submerged, Incompressible, Turbulent, Impinging Jets, David Tzeh-Hsian Lee

Theses

Measurements concerning various flow parameters of jets impinging on a smooth lucite plate and a heated metal plate have been carried out. In particular, it is shown that the potential core length of a jet is a function of the Reynolds number and of the jet diameter. It has also been demonstrated that impinging jets behave in many important respects like free jets, except in the immediate vicinity of the target plate.

The flow behavior in the wall jet zone was investigated experimentally, and a satisfactory agreement with the results of the previous investigators was found. The maximum velocity decay …

Financing The Nuclear Fuel Requirements Of Public Utilities, Peter A. Lewis

Theses

A major portion of new electric generating capacity will be nuclear powered. The change to nuclear power will require large outlays of capital not required with conventional fuels to finance nuclear fuel inventories. Nuclear fuel financing requirements are unique because nuclear fuel is not consumed in the same manner as conventional fuels. Financing has not been a problem to date because nuclear fuel can be obtained only through lease from the Atomic Energy Commission. This arrangement will be terminated by June 30, 1973 and from that date on all nuclear fuel must be privately owned. Electric utilities have shown an …

A Rheological Equation Of State For Blood At Low Shear Rates, Anatoly Dritschilo

Theses

In this work a new rheological equation of state is presented and its application to blood is studied. The equation considered is a linear combination of Newtonian and non-Newtonian contributions to the apparent viscosity. The general form of the equation is

 T_ij =-(A + Be^{-1/C|(.5)Δi/j:Δj/i|1/2})Δij

Data from the literature were used to test the equation by generating curves of measured torque (T/L) versus applied shear rate (Ω) that would characterize the behavior of blood at all red cell concentrations and all shear rates in the Gilinson, Dauwalter and Merrill viscometer. The constants for the equation were …

Aerial Oxidation Of Lith Developers, Joe Smith

Theses

Lith developers, unlike conventional developers, lose alkalinity when aerially oxidized. This is attributed to the alkaline reaction of the formaldehyde-bisulfite compound (FBS) commonly employed in lith developers as a "sulfite buffer". Conventional chemical analysis methods are used to obtain data and experimentally derive an equilibrium constant for the alkaline disassociation of FBS. Chemical and sensitometric data are presented that indicate that the alkalinity loss contributes significantly to the overall loss of developer activity. It is also shown that aeriating a lith developer quantitatively converts hydroquinone to hydroquinone monosulfonate that, in turn, is a measurably active developing agent. Additional data are …

Computer Specification Of Centrifugal Pump And Motor, Paul David O'Lenick

Theses

The purpose of this thesis is to develop a PORTRAIT computer program for selecting a centrifugal pump and motor driver. This is accomplished by means of generalized data which establishes the speed of the Dump and its power requirement. After selection of the pump, the motor is sized and specified. In addition to determining the pump and motor, the program also sizes the discharge and suction lines and the required control valve. The resulting solution yields the pump design data, motor, line and control valve sizes. From this data utility and relative equipment costs can be estimated.
