A clay sample has a void ratio of 0.50 in dry state and specific gravity of solids is 2.70. Its shrinkage limit will be
wm=eG×100=0.52.7×100
A sample of saturated sand has a dry unit weight of 18kN/m3 and a specific gravity of 2.7. If density of water is 10kN/m3, the void ratio of the soil sample will be
