87) If moisture content is 20%, void ratio is 0.66 & 2.7 is the specific gravity of soil then find the value of degree of saturation of soil?
- a) 88.88%
- b) 91.91%
- c) 81.81%
- d) 95.92%
Answer: c) 81.81%
- The specific gravity of soil, G=2.7
- Void ratio of soil, e=0.66
- The moisture content of the soil, w=20%=0.2
The formula of the degree of saturation is,
S = w G / e
S = (0.2 x 2.7) / 0.66
S = 0.8181
In percentage, the degree of saturation is 81.81%.
i.e., S =81.81%
