index= Tapped density - Bulk density / Tapped density x 100
In order to show the relative increase of the isentropic compressibility
, a ratio is determined in the following equation.
where [Z.sup.0] and [Z.sup.1] are the values of subentry of the compressibility
factor, which are nondimensional, and to is the acentric factor.
The values of bulk modulus increased when concentrations increased, this was caused due to the decrease of compressibility
(with [parallel]x[parallel] being the Frobenius norm), and chose [nabla][v.sub.2], if it existed, as one of the four unique matrices of the form [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] that give the same compressibility
p, but whose determinant and trace fulfill the conditions
Owing to the fact that the particles of waste materials are much larger than those of fine-grained soil, it is not possible to precisely determine the waste compressibility
by commonly used oedometers such as Casagerande oedometer.
The variation of Density, Viscosity, Velocity, adiabatic compressibility
(Pad), intermodular free length (Lf), relaxation time (X), free volume (Vf), internal pressure (ni), acoustical impedance (Z),constant (W), ultrasonic attenuation ([alpha]/f2), Rao's constant (R), molar volume (Vm), and cohesive energy (CE) of pyrimidine derivatives at 313 K in different concentrations are shown in Figures 1 to 13.
In this research different scenarios are designed to monitor the effect of rock and fluid compressibility
values on oil production.
The density data can then be used to calculate a Compressibility
Index (comparable to a Carr Index) and a Compressibility
Ratio (comparable to a Hausner Ratio).
In the next chapters the excellent compressibility
properties of the 1-ethyl-3-methylimidazolium ethylsulphate (EMIM-EtS[O.sub.4]) as an ionic liquid will be shown in comparison to the classical hydraulic mineral oil ISO VG 46, nonflammable HFD-Type hydraulic fluid Quintolubric 888-68, and water.
In modern diesel engine, the injection pressure of fuel spray system continuously was elevated to achieve better atomization, combustion, and emission effect and even reach 200 MPa or more, which increase vastly the dynamics sensibility of fuel compressibility
. The dynamic delivery process, which was carried out under rapid variation of pressure and temperature, was strongly affected by the compressibility
of fuel and its derivative properties relative to pressure and temperature.
The excess molar volumes ([V.sup.E]), viscosity deviations ([DELTA][eta]), excess Gibbs energy of activation ([G.sup.E]), deviations in isentropic compressibility
([K.sup.E.sub.S]), deviations in speed of sound ([u.sup.E]), and deviations in the molar refraction ([DELTA]R) were calculated from the experimental data.
