Specific Volumes of Water at High Pressures, Obtained from Ultrasonic-Propagation Measurements

Abstract

A computer‐aided procedure has been developed for obtaining specific volumes from measuredultrasonic velocities in any nondispersive medium. Newly measuredvelocities up to 80°C and 10 000 kg/cm2 have yielded values of specific volumes and a number of thermodynamic coefficients for water over this same range. P. W. Bridgman's measurements of specific volumes in the high‐pressure range showed systematic differences of a few tenths of a percent; the present calculations yield values believed to be good to 0.05% or better for most of the range.
