PHRQINPT--An Interactive Computer Program for Constructing Input Data Sets to the Geochemical Simulation Program PHREEQE

Description: Abstract: PHRQINPT is a FORTRAN 77 program that facilitates formulation of the input data file to PHREEQE (Parkhurst, Thorstenson, and Plummer, 1980). PHRQINPT runs interactively and contains many features to help the user construct the input data set. This report describes these features and gives instructions on the use and implementation of PHRQINPT. A listing of the program and the two accompanying data sets are given in the Attachments, along with two examples.

Physical and Chemical Properties of the Petroleums of the San Joaquin Valley of California

Description: From Introduction: "This bulletin is the second report so far published and deals primarily with the large oil fields of the San Joaquin Valley of California. The work will be continued as rapidly as possible, and will include all of the more important petroleum districts of the United States. The prime object of the investigations was to determine the economic value of the petroleums and natural gases in the United States with especial reference to the supplies in the public lands, and to ascertain how these resources could be utilized in the industries with least waste and greatest efficiency.

Physical and Hydrologic Environments of the Mulberry Coal Reserves in Eastern Kansas

Description: From introduction: The U.S. Geological Survey is currently conducting a two-phase investigation designed to provide hydrologic information about the coal-producing area in Miami, Linn, and Bourbon Counties of eastern Kansas (fig. 1). This report presents information to satisfy the objectives of the first phase of the investigation. These objectives are to: (1) assemble and interpret existing hydrologic data; (2) describe the physical and hydrologic environments based on existing data; and (3) determine additional data needed to evaluate the impacts of coal mining on the hydrology of the study area.

Physical Chemistry of the Fischer-Tropsch Synthesis

Description: From Summary: "This paper summarizes the results of physicochemical studies of the Fischer-Tropsch synthesis (the catalytic hydrogenation of carbon monoxide) undertaken by the Federal Bureau of Mines as part of its program on improving processes for producing liquid fuels from coal."

The physical effects of detonation in a closed cylindrical chamber

Description: Detonation in the internal-combustion engine is studied as a physical process. It is shown that detonation is accompanied by pressure waves within the cylinder charge. Sound theory is applied to the calculation of resonant pressure-wave frequencies. Apparatus is described for direct measurement of pressure-wave frequencies. Frequencies determined from two engines of different cylinder sizes are shown to agree with the values calculated from sound theory. An outline of the theoretically possible modes of vibration in a right circular cylinder with flat ends is included. An appendix by John P. Elting gives a method of calculating pressure in the sound wave following detonation.

Physical Environment and Hydrologic Characteristics of Coal-Mining Areas in Missouri

Description: From abstract: This report provides "hydrologic information for the north-central and western coal-mining regions of Missouri . . . to define the hydrologic system in these areas of major historic and planned coal development." It "describes the physical setting, climate, coal-mining practices, general hydrologic systems, and the current (1980) hydrologic data base in these two coal-mining regions."

Physical Hydraulic Models: Assessment of Predictive Capabilities; Report 1: Hydrodynamics of the Delaware River Estuary Model

Description: Partial abstract: The purpose of this study is to define the reliability with which results of tests conducted in a physical model of the Delaware River Estuary can be used to predict the effects of modifications to the estuary. The Delaware River model at the Waterways Experiment Station was used to conduct tests to predict the effects of the navigation channel enlargement between Philadelphia and Trenton, and the results of the tests are compared with subsequent prototype data to determine the accuracy of the model predictions.

Physical, Hydrological, and Biological Characteristics of the Loxahatchee River Estuary, Florida

Description: From purpose and scope: One of the objectives of the ongoing U.S. Geological Survey investigation of the Loxahatchee River estuary is to provide baseline information on the estuary. This map report was prepared to fulfill part of this objective. It provides information on bathymetry, hydrology, and benthic sediment and biota.

Physical Parameters in Synthoil Process, Quarterly Report: January-March 1976

Description: This work is being done in support of the development of processes for converting coal to liquid fuel of low sulfur content, suitable for use in power production. Most of the effort is intended to produce information applicable to the SYNTHOIL Process. In the SYNTHOIL Process for converting coal to a low-sulfur fuel oil, coal is liquefied and hydro-desulfurized in a turbulent-flow, catalytic packed-bed reactor. A slurry of coal in recycled oil is reacted with hydrogen at 450 degrees C and 2,000 to 4,000 psi in the presence of Co-MoSiO2-Al2O3 catalyst. The turbulent flow of fluid prevents the coal's mineral matter from settling and plugging the reactor. The gross liquid products are centrifuged to remove the unreacted solids. The centrifuged liquid product is a low-S, low-ash fuel. The following four tasks are included: (1) heat of reaction of hydrogen with coal slurries; (2) heat transfer coefficient; (3) additives to facilitate separation of solids from liquids; and (4) catalyst testing. These are now in the planning stage of development.
