γdry = {( γbulk)/(1+ω)}

ω = % of water content

Sample Number	1	2	3	4	5	6
γbulk kg/litre	1.8	1.94	2.0	2.005	2.003	1.98
% water content	8.5	12.2	13.75	15.5	18.2	20.2
γ dry	1.659	1.729	1.758	1.736	1.695	1.647

Maximum theoretical γdry = (G .γω)/(1+ ωG) (ω = 15.5%)

= (2.7 X 9.81)/(1+(0.155)X (2.7))

= 1/0.05355

= 18.6725 k N/m2
