2) The weight of a container is 40gm & the weight of the container and wet soil sample is 100gm. On oven drying for 24 hours, the weight of the container with dry soil is found to be 80gm. What is the water content of soil?
- a) 33.33%
- b) 40%
- c) 50%
- d) 50.8%
Answer: c) 50%
W1= Empty weight of the container = 40gm
W2= Weight of (Empty container + Wet soil sample) =100gm
W3= Weight of (Empty container + Dry soil sample) =80gm
W= Water Content=?
The formula of water content by oven drying method,
W = (W2-W3)/(W3-W1) x 100
W = (100-80)/(80-40) x 100
W = 50 %
Hence, the moisture content in a given soil sample is 50 %.
