The four graphs are titled Planar Void Ratio Air Pluviation for six-millimetre Diameter, zero point three zero five-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 six one nine, standard deviation zero point one one three, and maximum gradient thirty-nine point seven seven. For one Sieve, mean zero point six two eight, standard deviation zero point one seven eight, and maximum gradient twenty-eight point five six. For two Sieves, mean zero point six one seven, standard deviation zero point one one one, and maximum gradient thirty-five point two three. For three Sieves, mean zero point six zero nine, standard deviation zero point one one seven, and maximum gradient thirty-four point eight six.Comparison of void ratio variation of samples prepared from 0.610 m drop height using air pluviation and radius expansion method
