چکیده

A complete study of thermophysical properties concerning the 2-(2-diethylaminoethoxy)ethanol (DEAE-EO) + water binary system is realized. Density, speed sound, dynamic and kinematic viscosities refractive index measurements have been performed at atmospheric pressure, using a vibrating tube densitometer, falling ball viscosimeter, refractometer for pure DEAE-EO, water, aqueous solutions from 278.15 to 323.15 K. The thermal expansion was calculated density data. Excess Gibbs energy flow corresponding excess entropy were also considering viscosity molar (volume, isobaric coefficient, square index) Redlich-Kister equations applied correlate Thermophysical DEAE-EO (50 mol%) Methyldiethanolamine (MDEA) compared their application in absorption acid gases.

some properties of fuzzy hilbert spaces and norm of operators

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...

Measurement of Selected Thermophysical and Viscosity of Binary Mixtures of Nitromethane with 2-Propanol, 2-Butanol and 2-Pentanol

The density and viscosity values at T= (293.15 to 323.15) K for binary mixtures of nitromethane with 2-propanol, 2-butanol and 2-pentanol were measured over the entire composition range. From the experimental data, excess molar volumes, thermal expansion coefficients, excess thermal expansions, partial molar volumes at infinite dilution and deviations in viscosity were calculated. The results w...
