Speeds of sound for a biogas mixture + + + from = (1-12) MPa at = (273, 300 and 325) K measured with a spherical resonator
Daniel Lozano-Martín, José J. Segovia, M. Carmen Martín +2
The present work aims to measure speeds of sound in a biogas mixture of + + + , at = (1-12) MPa and = (273, 300 and 325) K, using a spheri…
Updated determination of the molar gas constant by acoustic measurements in argon at UVa-CEM
J J Segovia, D Lozano-Martín, M C Martín +5
A new determination of the molar gas constant was performed from measurements of the speed of sound in argon at the triple point of water and extrapolation to zero pressure. A new…
A novel technique based on a cylindrical microwave resonator for high pressure phase equilibrium determination
Rodrigo Susial, Ángel Gómez-Hernández, Daniel Lozano-Martín +3
The development of a novel technique based on a cylindrical microwave resonator for high pressure phase equilibrium determination is described. Electric permittivity or dielectric…
Speeds of sound for ( + ) mixtures from = (0.5 to 20) MPa at = (273.16 to 375) K
Daniel Lozano-Martín, Andres Rojo, M. Carmen Martín +2
This work aims to provide accurate and wide-ranging experimental new speed of sound data (,) of two binary ( + ) mixtures at a nominal helium content of 5% and…
Speed of sound and phase equilibria for ( + ) mixtures
Daniel Lozano-Martín, Rodrigo Susial, Pedro Hernández +3
This work presents phase envelope and speed of sound data for the (0.60 + 0.40 ) and (0.80 + 0.20 ) binary mixtures. Phase equilibria was…
