a Unit Weight of Sand (pcf) SFN 59724
b Wt. material removed from test hole-lbs.
c Initial sand weight - lbs.
d Final sand weight - lbs.
e Wt. sand in funnel and hole = c - d
f Cone calibration factor- lbs. SFN 59724
g Wt. sand in hole = e - f (lbs.)
h Volume of test hole = g/a (cu. ft.)
l Wet Density = b/h/(lbs./cu. ft.)
j Dry Density = i/(100+p) x 100(lbs./cu.ft.)
Moisture Determination
k Wet weight + container
l Dry weight + container
m Moisture loss = k - l
n Tare weight of container
o Dry weight of soil = l - n
p Moisture Percentage = (m/o) x 100 (%)
