The project was concerned with the study of various nonequilibrium processes, specifically those that can be conducted at a steady rate. New experimental data were interpreted on the basis that the properties of terminal stationary states define the steady flow of heat, mass, andor volume across a gradient region. Data are reported for four liquids, water, carbon tetrachloride, chlorobenzene, and n-butanol, in steady force vaporization from five circular glass tubes with areas from 11 to 285 sq. mm at three temperatures, 50, 25, and near 2C over wide pressure ranges. One major point of emphasis was that data reduction is reliably established by properties of well-defined terminal regions. This is in contrast to the usual kinetic and heat-transfer approaches, in which gradients pose a serious problem for experimental verification on a microscopic basis surface temperatures in accommodation experiments are a good example. The status of the program is reviewed, and a list of accomplishments and publications is given. Author
