Porosity formula using vol fraction
WebThe formation of the χ phase is preceded by a strong anisotropic increase of the unit-cell vol. of realgar and the β phase. The effects of light exposure on lattice parameters were studied using single-crystal X-ray diffraction: in realgar a and c sin β increase linearly with increasing exposure times, whereas b remains substantially unchanged. Webfraction, and the remaining fraction is that of the voids. The void fraction is also called the voidage and the bed porosity. It is important to realise that, in liquid systems, the voids are usually filled with liquid and not to assume that the bed consists of just solids and air. The porosity is usually an isotropic property (i.e. the same in all
