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.

A new technique for the accurate (1-0.01%) determination of transport and thermodynamic properties of gases is described. This technique consists of measuring the linewidth of a small acoustic resonator. The linewidth of more than one type of resonance allows the transport properties (thermal conductivity and viscosity) to be determined independently. The center frequency gives the sound speed. The theory of the acoustic resonator is presented including the effects of relaxation in the gas, slip and accommodation on the cavity walls, and acoustic transmission into the walls. The contributions of transducer coupling and feed through are also included in the cavity theory. Realization of cavities and transducers suitable (but not optimized) for measurements at temperatures up to 1000K and pressures up to 500 atm are discussed. Measurements employing the resonator technique are presented in Ar, N2, air and H2. High pressure measurements (p

Viscosities and thermal conductivities, suitable for heat-transfer calculations, were estimated for about 200 gases in the ground state from 100° to 5000° K and 1-atm pressure. Free radicals were included, but excited states and ions were not. Calculations for the transport coefficients were based upon the Lennard-Jones (12-6) potential for all gases. Intermolecular force constants for this potential were obtained from experimental viscosity data or were estimated when data were not available. The same set of constants was used to calculate both viscosity and conductivity. An Eucken-type correction for exchange between internal and translational energies was made for thermal conductivities of polyatomic gases.
