Once we got this data we have to bring some changes .To plot this data to the graph we need to find dry density because our graph is dry density against the water content. First of all we need to find the bulk/moist density as follow:

We have formula

ρ¿ massvolume

After we found the bulk/moist density our data is as follow:

Moisture content (%)

12 14 16 18 20 22

Bulk density kg/m3

1864.41 1970.34 2033.90 2055.08 2033.90 2012.71

As we mentioned before that our graph is dry density against water content, so we need to find the dry density. We can find dry density as follow:

We have formula

ρd= ρ1+w

As we calculated the dry density we have

Moisture content (%)

12 14 16 18 20 22

dry density kg/m3

1664.65 1728.37 1753.36 1741.59 1694.92 1649.76
