  • Question 6/7
    1 / -0
    A mass of soil coated with thin layer of paraffin wax weighs 575.60 gms and the soil alone weighs 560 gms. When the soil is immersed in water, if displace 320 ml of water. If specific gravity of soil and paraffin wax is 2.67 and 0.90 respectively and the water content of the soil is 18%. Calculate the degree of saturation (in percentage) of soil sample.
  • Question 7/7
