Answer: d) 40 KN
- Weight of given soil sample, W=190KN
- Weight of soil sample after oven drying, =150KN.
When we subtract the soil sample’s dry weight from the soil sample’s given weight, we will get the value of the weight of water.
i.e., Weight of Water, Ww = W- Wd
Ww = 40KN
Therefore, the weight water before the oven drying process is 40KN.
