Correlation for the Second Virial Coefficient of Water

March 4, 2004
Author(s)
Allan H. Harvey, Eric W. Lemmon
A new correlation has been developed to represent the second virial coefficient of water (H2O) as a function of temperature. The formulation was fitted to experimental data, both for the second virial coefficient itself and for a quantity related to its

ThermoML - An XML-Based Approach for Storage and Exchange of Experimental and Critically Evaluated Thermophysical and Thermochemical Property Data 2. Uncertainties

May 26, 2003
Author(s)
Robert D. Chirico, Michael D. Frenkel, Vladimir Diky, K N. Marsh, R C. Wilhoit
ThermoML is an XML-based approach for storage and exhange of experimental and critically evaluated thermophysical and thermochemical property data. Extensions to the ThermoML schema for the expression of uncertainties are described. Basic principles, scope

Thermodynamics of Enzyme-Catalyzed Reactions

March 1, 2003
Author(s)
Robert N. Goldberg, Yadu D. Tewari
This review, which has been prepared for the McGraw-Hill 2003 Yearbook of Science and Technology, gives an overview of the thermodynamics of enzyme-catalyzed reactions. Topics include the thermodynamic formalism(s) used in this field, computational methods

Arsenic Thermodynamic Data and Environmental Geochemistry

January 1, 2003
Author(s)
D K. Nordstrom, Donald G. Archer
Thermodynamic data are critical as input to models that attempt to interpret the geochemistry of environmentally important elements such as arsenic. Unfortunately, the thermodynamic data for mineral phases of arsenic and their solubilities have been highly

Thermodynamic Quantities for the Ionization Reactions of Buffers in Water

December 1, 2002
Author(s)
Robert N. Goldberg, N Kishore, R M. Lennen
This table contains selected values for the pK, standard molar enthalpy of reaction {Δ} rH , and standard molar heat-capacity change {Δ} rC p for the ionization reactions of 64 buffers many of which are relevant to biochemistry and to biology. The values

Acoustic Measurements in Gases, Chapter 10

September 15, 2001
Author(s)
Michael R. Moldover, Keith A. Gillis, John J. Hurly, J B. Mehl, J Wilhelm
Cylindrical acoustic resonators developed at the National Institute of Standards and Technology (NIST) are routinely used to measure the speed of sound in gases with uncertainties of 0.01% or less. The pressure dependence of the data is fitted with model

Speed of Sound as a Thermodynamic Property of Fluids

September 15, 2001
Author(s)
Daniel G. Friend
In this chapter, we review the principles of sound propagation in fluid systems. From a study of the hydrodynamic equations, sound propagation is shown to be a wave phenomenon. The speed of sound then can be derieved at any state point from a knowledge of

Vapor Entraining Magnetic Mixer for Reaction and Equilibrium Applications

March 1, 2001
Author(s)
Thomas J. Bruno, Michael C. Rybowiak
Mixing of fluids is a central component to innumerable operations in chemical processing on the plant floor and also in many laboratory operations. Most mixing applications simply require the efficient blending of fluids present in a single phase, such as
