Applying the principle of superposition, the equation to generate dimensionless well shut-in pressure is(16)pwDs=2.451CfD[tpDxf0.25−(tpDxf+ΔtDxf)0.25+ΔtDxf0.25] If tpDxf>>ΔtDxf, then tpDxf+ΔtDxf≅tpDxf and the right side of Eq. (16) can be simplified as(17)pwDs=2.451CfD...
Our results demonstrated that the 2D (CH3–(CH2)9)2NH2Cl undergoes interlayer expansion as large as 13% along the length direction of carbon chains (caxis) whileabplane remains nearly unchanged, consequently volume expansion as much as 12% occurs during phase transition. Such anisotropic expansion...
Monte Carlo calculations of the elastic moduli and pressure-volume-temperature equation of state for hexahydro-1,3,5-trinitro-1,3,5-triazine Isothermal-isobaric Monte Carlo calculations were used to obtain predictions of the elastic coefficients and derived engineering moduli and Poisson ratios ... ...
A Redlich-Kwong type of equation of state for gaseous CO2 with a and b being functions of molecular volume is proposed. This equation fits observed P-V-T data for gaseous CO2 from -50o to 1000oC and from 1 bar to 10 kbar, and predicts observed heat capacity values quite well. Geoche...
1.22.3.2High-Pressure Stopped-Flow and Temperature-Jump Stopped-Flow Instruments Pressureand temperature are boththermodynamic parameters. Changes in temperature simultaneously perturb both volume and internal energy, whereas pressure changes contribute to a change in volume and temperature of a system. The...
The γ angle of the monoclinic unit cell increases continuously above the transition. A Birch-Murnaghan equation of state fit to pressure-volume data obtained for KAlSi3O8 hollandite yields a bulk modulus K0 = 201.4 (7) GPa with K'0 = 4.0. 展开 ...
Eilerts and Smith (1942) correlated PDew with temperature (T), composition, molal average boiling point, and oil-to-gas volume ratio. Studying the reservoir fluid samples from the Paloma field, Olds et al. (1945) concluded the influence of composition on the PDew. These authors found that...
Crystal structures of magnesite (a) and magnesite-II (b). Full size image As seen in Fig. 1, Magnesite has a hexagonal crystal system with rhombohedral symmetry and space group R3¯c. The structural parameters, isothermal bulk modulus and equation of state for magnesite are determined from ...
