17. Kick's law (1885) the energy required to reduce a material in size is directly proportional to the size reduction ratio dL/L, that is the ratio of the initial particle size to the finial particle size This implies that P equal to 1. If P = 1 then 2 1 ln L L CE putting C = KKfc gives: 2 1 ln L L fKE cK KK is not dimensionless.
