Steam and Gas Tables with Computer Equations

Book excerpt: Steam and Gas Tables with Computer Equations presents tables illustrating the thermodynamic properties of steam and air, along with computer equations. Additional equations for a number of other gaseous substances which are useful in engineering investigations are included. This book is comprised of two chapters and begins with a discussion on the thermodynamic properties of steam, which can be divided into saturation and superheat properties. The various thermodynamic properties, including saturation temperature and pressure and liquid and vapor saturation entropy, are represented with three basic types of equations from the triple point to the critical point. The accuracy of the properties calculated from the base data is also considered. The next chapter deals with the thermodynamic properties of air and other gases (ethane, hydrogen, methane, nitrogen, oxygen propane, n-butane), including those properties which are useful in engineering design and analysis (specific heat at constant pressure and volume, enthalpy and entropy function, isentropic pressure function, etc). This monograph will serve as a useful guide for chemists, mathematicians, and computer programmers and scientists.
