A Critical Review of Second Virial Coefficients for Water Vapor with Air and With Argon

Published

Author(s)

Peter H. Huang, Allan H. Harvey

Abstract

This work reviews the current state of knowledge for the second virial coefficients of water vapor with air and with argon. Comparative tabulations of the coefficients are given from -20 degrees C to 100 degrees C along with the associated uncertainties. For Ar-H2O a pair potential produced by ab initio quantum calculations achieves a smaller uncertainty in the second virial coefficient than experiment. For Air-H2O, the existing experimental data are fairly well established in this temperature range, with uncertainties small enough for most purposes.
