CEG 3011 – Soil Mechanics Spring 2010 Homework 3 PROBLEM 1 The moist weight of 0.1 cubic feet of soil is 12.2 lb. If the moisture content is 12% and the specific gravity of soil solids is 2.72, determine the following: a.- Moist unit weight. b.- Dry unit weight. c. Void ratio. d. Porosity. e.- Degree of saturation f.- Volume occupied by the water. PROBLEM 2 For a given soil, the following are known: G = 2.74, moist unit weight ( γ ) = 20.6 kN/m³ and moisture content (w) = 16.6. Determine: a.- Dry unit weight. b. Void ratio. c. Porosity. d.- Degree of saturation e.- Determine the weight of water (in kN) to be added per cubic meter (m³)of soil for 100% of

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
