Several semi-empirical modified equations for the pore size and porosity had been suggested depending on the parameters affecting them for sphere particles of mono, binary and ternary packing systems. The parameters affecting the pore size were found to be the particle diameter, the porosity of the bed and the permeability to fluid flow. The parameters affecting the porosity in the packed bed of sphere packing are the particle and bed diameters. Several types of packing materials with different sizes have been used in the packed bed, and each had been studied separately.

Binary mixtures of three, selected Iraqi crude oils had been subjected to density measurements at temperatures 15, 25, 30C and precise data had been acquired on the volumetric behavior of these systems. The results are reported in terms of equations for excess specific volumes of the mixtures.
