The following are the results of a laboratory consolidation test on a soil specimen dry mass of specimen =120g, the height of specimen at the beginning of the test =3.40 cm, Gs =2.64, the diameter of the specimen = 40 cm

Effective pressure (KN/m²) 0, 20, 40, 60, 90, 150, 200, 400, 900, 1600 and 3400

Final height of the specimen at the end of consolidation, H (cm) 2.740, 2.700, 2.630, 2.520, 2.450, 2.323, 2.323, 2.224, 2.125, 2.112, and 2.100.

Find the following;

(a).  Height of solids
