The four graphs are titled Planar Void Ratio Radius Expansion for six-millimetre Diameter, zero point six one zero-metre Drop Height, with zero Sieve, one Sieve, two Sieves, and three Sieves. The horizontal axis is Planar Void Ratio from zero point two to one point eight. The vertical axis is Cumulative Density from zero to one point zero. Each graph includes an empirical cumulative distribution function curve, a Normal Distribution Fit curve, and a Lognormal Distribution Fit curve. For zero Sieve, the legend lists mean zero point seven six seven, standard deviation zero point one zero three, and maximum gradient thirty-five point two four. For one Sieve, mean zero point seven eight nine, standard deviation zero point one eight eight, and maximum gradient eighteen point four one. For two Sieves, mean zero point seven seven four, standard deviation zero point one zero eight, and maximum gradient thirty-three point zero four. For three Sieves, mean zero point seven seven six, standard deviation zero point zero nine nine, and maximum gradient twenty-seven point seven nine.Empirical cumulative density function of planar void ratio of 6 mm spherical particles specimen prepared by air pluviation from 0.610 m drop height with various numbers of sieves
