Providing an illustration of sound propagation in the Hormoz Strait ,this paper is about acoustic wave propagation in shallow water for a harmonic point source with low frequency, less than 1000 and solution of a homogenous Helmholtz equation using parabolic equation. C++ programming is used to solve Helmholtz equation [9] and MATLAB software is used to illustrate figures and animate them [6], ...
Petro-physical parameters of the reservoir (porosity, permeability, water saturation) are the most important parameters of oil and gas reservoirs. Economic appraisals of oil and gas reservoirs, as well as management and planning for the production and development of these reservoirs are not possible without the estimation of petro-physical parameters. Since measurements of these parameters are ...
Several different topological indices (the carbon number, the Wiener index, the Balaban dis tance sum connectivity index, the Randic molecular identification number, and the Randic molecular connectivity indices °/, 2%, 3̂ p and 3/ c) were employed in the correlation of the velocity of ultrasonic sound in a variety of alkane and alcohol species. Using linear regression analyses and published so...
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 len...
