Exploratory Study of Brine Disposal Using Fluid-Bed Evaporation

Exploratory Study of Brine Disposal Using Fluid-Bed Evaporation

Date: November 1971
Creator: LaMont, P. E.
Description: Report concerning fluid-bed evaporation as a possible method of separating waste brine into salts and pure water. Two process operations are examined: "(1) feed introduction to the evaporator through submered tubes, and (2) fludizization of soluble salt particles by superheated steam" (p. viii).

The First Spectrum of Hafnium (HF I)

The First Spectrum of Hafnium (HF I)

Date: July 1976
Creator: Meggers, William F.
Description: Report continuing W. K. Meggers' previous analysis in LS-coupling. This coupling is not rigorous in Hf I, and many intervals are irregular. Consequently, the levels are given also in numerical order with the even and odd levels presented in separate tables. The long line lists are given in two Appendices: Appendix A contains the observed Zeeman data for the individual lines, 531 in all; Appendix B consists of the complete line list of observed and classified lines. By far the greater part of the analysis is that of Meggers.

Date: 1974
Creator: Skinner, Eugene H.
Description: Report issued by the U.S. Bureau of Mines discussing the Flathead Tunnel in Montana. As stated in the introduction, "this information circular is a Bureau of Mines review of tunneling practices typical of the late 1960's. The report provides reference to all pertinent data related to the geology, mining operations, and ground support practices for the Flathead Tunnel" (p. 2). This report includes maps, tables, illustrations, and photographs.

Flow and Drag Formulas for Simple Quadrics

Flow and Drag Formulas for Simple Quadrics

Date: December 1, 1979
Creator: Zahm, A. F.
Description: The pressure distribution and resistance found by theory and experiment for simple quadrics fixed in an infinite uniform stream of practically incompressible fluid are calculated. The experimental values pertain to air and some liquids, especially water; the theoretical refer sometimes to perfect, again to viscid fluids. Formulas for the velocity at all points of the flow field are given. Pressure and pressure drag are discussed for a sphere, a round cylinder, the elliptic cylinder, the prolate and oblate spheroid, and the circular disk. The velocity and pressure in an oblique flow are examined.

Flow and Force Equations for a Body Revolving in a Fluid

Flow and Force Equations for a Body Revolving in a Fluid

Date: December 1, 1979
Creator: Zahm, A. F.
Description: A general method for finding the steady flow velocity relative to a body in plane curvilinear motion, whence the pressure is found by Bernoulli's energy principle is described. Integration of the pressure supplies basic formulas for the zonal forces and moments on the revolving body. The application of the steady flow method for calculating the velocity and pressure at all points of the flow inside and outside an ellipsoid and some of its limiting forms is presented and graphs those quantities for the latter forms. In some useful cases experimental pressures are plotted for comparison with theoretical. The pressure, and thence the zonal force and moment, on hulls in plane curvilinear flight are calculated. General equations for the resultant fluid forces and moments on trisymmetrical bodies moving through a perfect fluid are derived. Formulas for potential coefficients and inertia coefficients for an ellipsoid and its limiting forms are presented.
