Powers Equation

As as in the experiment with monosized spheres, the Powers equation is only compared to the measurements of the 95 th percentile of the paste-void spacing distribution. As in the case of monosized spheres, the Powers equation is directly proportional to the 95 th percentile. However, for this distribution of lognormally distributed sphere radii, the Powers equation is a constant factor of 1.5 larger than the 95 th percentile.
