In this study for the first time a new description of compressibility factor is rendered based on the virial expansion. The compressibility factor as a function of M-factor is qualitatively and quantitatively expressed. At first, we present how may the third, fourth and higher order virial coefficients be logically ignored in order to simplify the virial equation. The results show, wh...

The density (ρ) and ultrasonic velocity (U) for ternary mixture of dimethyl acetamide, isobutyl methyl ketone and diethyl ether at different frequencies (2MHZ, 4MHz, 6MHZ, 8MHZ) have been measured at 308K. These data have been used to compute adiabatic compressibility (Ks), intermolecular free length (Lf), acoustic Impedance (Z), molar volume (Vm), molar sound velocity(R), molar compressibility...

We show how to obtain the critical compressibility factor Z(c) for simple and associative Lennard-Jones fluids using the critical characteristics of the Ising model on different lattices. The results show that low values of critical compressibility factor are correlated with the associative properties of fluids in critical region and can be obtained on the basis of the results for the Ising mod...

Compressibility of liquid flame spray-deposited porous TiO2 nanoparticle coating was studied on paperboard samples using a traditional calendering technique in which the paperboard is compressed between a metal and polymer roll. Surface superhydrophobicity is lost due to a smoothening effect when the number of successive calendering cycles is increased. Field emission scanning electron microsco...

RIFT (Resin Infusion under Flexible Tool) process modelling requires accurate material data like resin viscosity, reinforcement compressibility and reinforcement permeability. During the mould closing, the compression phase and the resin flow are important stages that strongly influence the quality of the obtained parts. In RIFT process the upper mould is a formable vacuum bag: its flexibility ...

Using subsurface charge accumulation scanning microscopy, we image strips of low compressibility corresponding to several integer quantum Hall filling factors. We study in detail the strips at Landau level filling factors n52 and 4. The observed strips appear significantly wider than predicted by theory. We present a model accounting for the discrepancy by considering a disorder-induced nonzero...

We describe the liquid-gas transition in the hard sphere system with Yukawa tail interactions in the mean spherical approximation. The dependence of critical temperature and density on the range of the interaction is shown and the spinodal curve for a short-ranged potential and a long-ranged potential is presented. The compressibility, energy and virial pressures are presented for a long-ranged...

alkanolamine solutions such as 2-amino-2-methyl-1-propanol (amp) are widely used in chemical industries for the removal of acid gases such as co2 and h2s. in this work, the density of co2, amp, water, and amp solutions using the goharshadi–morsali–abbaspour equation of state “gma eos” in the extended 50-degree range of temperatures (313.06-362.65 k) and pressures (0.5-40 mpa) was calculated. th...

The aim of the present study was to prepare an oral tablet from liquid yogurt by reforming the physical properties for easy transportation, long-term storage and also as a complementary dairy product in case of nutrient deficiency. The liquid fresh yogurt was lyophilized at -40°C and 0.03 mTor pressure. The dry powder was homogenized by a 12 mesh size sieve. Some tests such as Carr's compressib...
