Latest Equation of state Stories
The idea of compressing water is foreign to our daily experience. Nevertheless, an accurate estimate of water’s shrinking volume under the huge gravitational pressures of large planets is essential to astrophysicists trying to model the evolution of the universe. They need to assume how much space is taken up by water trapped under high density and pressure, deep inside a planet, to calculate how much is needed of other elements to flesh out the planet’s astronomical image. In a...

This summer, one of the world's leading ocean science bodies, the United Nations Educational, Scientific and Cultural Organization's (UNESCO's) and Intergovernmental Oceanographic Commission (IOC) adopted the new international thermodynamic equation of state for seawater called TEOS-10. A complex, dynamic mixture of dissolved minerals, salts, and organic material, seawater has historically presented difficulties in terms of determining its physical chemical properties.For 30 years, climate...
Technique may provide data for NIF nuclear fusion effort The enormous pressures needed to melt diamond to slush and then to a completely liquid state have been determined ten times more accurately by Sandia National Laboratories researchers than ever before.As a bonus to science, researchers Marcus Knudson, Mike Desjarlais, and Daniel Dolan discovered a triple point at which solid diamond, liquid carbon, and a long-theorized but never-before-confirmed state of solid carbon called bc8 were...
Proposed new international 'equation of state' employs absolute over practical salinity to redefine thermodynamic equation of seawater after 30 yearsSeawater is a complex, dynamic mixture of dissolved minerals, salts, and organic materials that despite scientists best efforts, presents difficulties in measuring its potential to contain and disperse energy. Like the water itself, the calculations scientists employ to measure seawater are fluid, undergoing significant revisions and...
By Bahadori, Alireza Gas Processing A new numerical model predicts the amount of H S and CO2 absorbed per volume of different glycols circulated vs. the partial pressure of acid-gas components and the absorber's temperature. The model covers the full range of dehydration-plant operating conditions and a wide range of experimental data results. This study shows that the proposed approach is more accurate than routine equations of state approaches in predicting the solubility of acid gases...
