Using the replica trick we derive a formalism to describe the structure and the thermodynamic properties of a binary liquid in equilibrium with a porous medium. We present the replica Ornstein-Zernike equations for the general case of a k-component liquid inside a porous matrix; besides the usual liquid-state closure relations, we consider in particular the optimized random phase approximation ...

In this investigation, silica fume (SF) was used as an additive material to study its influence on the characteristics of expansive soil. The soil in research prepared a lab by mingling bentonite (50 percent dry weight) with natural According (USCS), classified (CH) liquid limit 67.5 and plastic 29.3%. Expansive mixed different percentages (SF), (8, 9, 10, 11, 12, 13%), experiments were conduct...

Compressibility factor and viscosity of natural gasses are of great importance in petroleum and chemical engineering. To calculate the natural gas properties in the pipelines, storage systems and reservoirs, the exact values of gas compressibility factor and viscosity are required. A new method that allows accurate determination of compressibility factor and gas viscosity for all types of: swee...

the ultrasonic velocity, density and viscosity of some schiff bases of 4-amino benzoic acid  were measured in 1,4-dioxane and dimethylformamide at 308.15 k. various acoustical properties such as isentropic compressibility (ks), rao’s molar sound function (rm), the van der waals constant (b), molar compressibility (w), inter molecular free length (lf), relaxation strength (r), internal pressure ...

based on the carnahan and starling hard sphere equation of compressibility, an equation of state has been derived. conditions that must be met by all equations of state are applied in order to obtain attractive term or non - ideal compressibility term of the equation. second virial coefficient and acentric factor arc used in the derivation of the equation of state. in this equation, compressibi...

Anomalous behavior of water has been a long standing problem in physical and chemical sciences. The seeming divergence of response functions such as specific heat, compressibility, and coefficient of thermal expansion at low temperatures T , have been interpreted by some authors as the evidences for the liquid-gas spinodal retracing back to positive pressures P at low temperatures. Other author...

Liquid water is the most intriguing liquid in nature, both because of its importance to every known form life, and numerous anomalous properties, largely magnified under supercooled conditions. Among properties seeming divergence thermodynamic response functions dynamic below homogenous nucleation temperature (~ 232 K). Furthermore, exhibits an increasingly decoupling viscosity diffusion, upon ...
