Question

By the use of consolidometer, _________ gives direct measurement of permeability.

(a) only fixed ring type

(b) only floating ring type

(c) both fixed and floating ring type

(d) both fixed and floating ring type don’t give direct measurement

I got this question in an interview for internship.

The above asked question is from Laboratory Consolidation Test in portion One Dimensional Consolidation of Geotechnical Engineering I

Answer 1

The correct choice is (a) only fixed ring type

The best explanation: By the use of consolidometer, only fixed ring type gives direct measurement of permeability and not the floating ring type consolidometer. This is because only the top porous stone is allowed to compress the specimen.
