Apparent densities have been measured of glass beads of various shapes, to study the effect of the shaped factor on bad porosity. It was found that the porostiy was ilnerly realted to the shape factor. The densites were carried out in graduates of different diameters to study the wall effect. It was found that the porosity (ϵe) is a function of gradute diameter (D) by a function of the type; in[ϵe-Q] = - kD + q, where Q is the samllest porosity under the pouring and shaking condtions.
