Question

The voids ratio with respect to height of solids is given by equation______________

(a) \(e=\frac{H}{H_s}\)

(b) \(e=\frac{H_s}{H}\)

(c) \(e=\frac{H+H_s}{H_s}\)

(d) \(e=\frac{H-H_s}{H_s}\)

I got this question in an internship interview.

This intriguing question comes from Calculation of Voids Ratio and Coefficient of Volume Change in chapter One Dimensional Consolidation of Geotechnical Engineering I

Answer 1

Correct option is (d) \(e=\frac{H-H_s}{H_s}\)

To explain I would say: The voids ratio is calculated from the equation of,

\(e=\frac{H-H_s}{H_s},\) where e=voids ratio

H=height of specimen at equilibrium

Hs= height of solids.
