Experimental Thermodynamics

Book excerpt: Experimental Thermodynamics, Volume II: Experimental Thermodynamics of Non-reacting Fluids focuses on experimental methods and procedures in the study of thermophysical properties of fluids. The selection first offers information on methods used in measuring thermodynamic properties and tests, including physical quantities and symbols for physical quantities, thermodynamic definitions, and definition of activities and related quantities. The text also describes reference materials for thermometric fixed points, temperature measurement under pressures, and pressure measurements. The publication takes a look at absolute measurement of volume and equation of state of gases at high temperatures and low or moderate temperatures. Discussions focus on volumes of cubes of fused silica, density of water, and methods of measuring pressure. The text also examines the compression of liquids and thermodynamic properties and velocity of sound, including thermodynamics of volume changes, weight methods, and adiabatic compression. The selection is a dependable reference for readers interested in the thermophysical properties of fluids.
