Thermodynamic Properties of Cryogenic Fluids This update to a classic reference text provides practising engineers and scientists with accurate thermophysical property data for cryogenic fluids. The equations for fifteen important cryogenic fluids are presented in a basic format accompanied by pressure enthalpy and temperature entropy charts and tables of thermodynamic properties. It begins with a chapter introducing the thermodynamic relations and functional forms for equations of state and goes on to describe the requirements for thermodynamic property formulations needed for the complete definition of the thermodynamic properties of a fluid. The core of the book comprises extensive data tables and charts for the most commonly encountered cryogenic fluids. This new edition sees significant updates to the data presented for air argon carbon monoxide deuterium ethane helium hydrogen krypton nitrogen and xenon. The book supports and complements NIST’s REFPROP an interactive database and tool for the calculation of thermodynamic properties of cryogenic fluids.
