Answer: b) 0.865
Explanation:
Given Data:
- Dry density soil, γd = 17.5 KN/m3
- Maximum dry density of soil, γd(max.) = 18.5kN/m3
- The minimum dry density of soil, γd(min.) = 13kN/m3
The formula of relative density is given below,
ID= ([γd-γ(min)] γd(max.))/([γd(max.)-γd(min.)]γd)
ID = [17.5-13]x18.5/(18.5-13)x17.5
ID = 0.865
Hence, the relative density of soil is found to be 0.865
