Question

The height HS of the solids of the specimen is calculated from _______________

(a) \(H_s=\frac{M_d}{GA}\)

(b) \(H_s=\frac{M_d}{Gρ_w}\)

(c) \(H_s=\frac{M_d}{Aρ_w}\)

(d) \(H_s=\frac{M_d}{GAρ_w}\)

The question was posed to me in quiz.

The query is from Calculation of Voids Ratio and Coefficient of Volume Change in portion One Dimensional Consolidation of Geotechnical Engineering I

Answer 1

Right option is (d) \(H_s=\frac{M_d}{GAρ_w}\)

To elaborate: The height HS of the solids of the specimen is calculated from the expression,

\(H_s=\frac{M_d}{GAρ_w},\)

where, Hs=height of solids

Md=mass of dried soil sample

G=specific gravity of solid particles

A=cross-sectional area of specimen

ρw=mass density of water.
