pie was taken with a cylindrical metal core having a volume 300 cm3. The soil was saturated with water and then drainage water wa allowed to drip. Meanwhile, evaporation of water from the soil wa prevented. The drained soil sample weighed 500 g before oven dryin and 350 g after oven drying. Calculate the following: a. bulk density (Pb) b. moisture content by mass(%0m) and by volume (%0v) C. porosity (assume ps 2.65 g/cm3) %D

Question
3. A soil sample was taken with a cylindrical metal core having a volume of
300cm³. The soil was saturated with water and then drainage water was
allowed to drip. Meanwhile, evaporation of water from the soil was
prevented. The drained soil sample weighed 500 g before oven drying
and 350 g after oven drying. Calculate the following:
a. bulk density (p6)
b. moisture content by mass(%0m) and by volume (%0v)
c. porosity (assume ps = 2.65 g/cm³)
d. cm of water per 100 cm depth of soil
%3D
