Download or read book Thermophysical Properties of Helium 4 from 0 8 to 1500 K with Pressures to 2000 Mpa written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-23 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tabular summary data of the thermophysical properties of fluid helium are given for temperatures from 0.8 to 1500 K, with pressures to 2000 MPa between 75 and 300 K, or to 100 MPa outside of this temperature band. Properties include density, specific heats, enthalpy, entropy, internal energy, sound velocity, expansivity, compressibility, thermal conductivity, and viscosity. The data are calculated from a computer program which is available from the National Institute of Standards and Technology. The computer program is based on carefully fitted state equations for both normal and superfluid helium. Arp, Vincent D. and Mccarty, Robert D.

Download or read book International Thermodynamic Tables of the Fluid State Helium 4 written by S. Angus and published by Elsevier. This book was released on 2016-04-20 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: International Thermodynamic Tables of the Fluid State Helium-4 presents the IUPAC Thermodynamic Tables for the thermodynamic properties of helium. The IUPAC Thermodynamic Tables Project has therefore encouraged the critical analysis of the available thermodynamic measurements for helium and their synthesis into tables. This book is divided into three chapters. The first chapter discusses the experimental results and compares with the equations used to generate the tables. These equations are supplemented by a vapor pressure equation, which represents the 1958 He-4 scale of temperature that is defined in terms of the vapor pressure of helium-4. The second chapter are devoted to various equation of state used for the determination of thermodynamic properties. The third chapter contains IUPAC Tables, including their construction, limits, use, and accuracy. This book will be of value to physical chemists and researchers in the field.
