An unconfined compression test is performed on a dense silt. Previous drained triaxial tests on similar samples of the silt gave ∅' = 32o. If the unconfined compressive strength was 420 kPa, estimate the height of capillary rise in this soil above the ground water table. (Hint: Find the effective confining pressure acting on the specimen. Draw elements similar to Fig. 12.40.)
