01 Soil Properties Situation 1 ▣ 1. Moist Unit Weight of the Soil (kN/m3 ) [SOLUTION] Formula for Moist Unit Weight γm = Wm V γm = mmg V γm = (30.6 kg) (9.81 m s 2 ) 0.0183 m3 γm = 16. 4 kN m3 ▣ 2. Dry Unit Weight of the Soil [SOLUTION] Formula for Dry Unit Weight γd = Wd V = mdg V γd = (27.2 kg) (9.81 m s 2 ) 0.0183 m3 γd = 14. 6 kN m3 ▣ 3. Moisture Content [SOLUTION] Formula for Moisture Content ω = Wm − Wd Wd = Mm − Md Md
ω = 30.6 kg − 27.2 kg 27.2 kg ω = 0. 125 = 12. 5% ▣ 4. Void Ratio [SOLUTION] Formula for Moist Unit Weight γm = G(1 + ω) 1 + e ∗ γw 16.4 kN m3 = 2.65(1 + 0.125) 1 + e ∗ (9.81 kN m3 ) e = 0. 783 ▣ 5. Porosity [SOLUTION] Formula for Porosity given Void Ratio η = e 1 + e η = 0.783 1 + 0.783 η = 0. 439 ▣ 6. Degree of Saturation [SOLUTION] Relationship of Soil Properties Se = ωG S ∗ (0.783) = (0.125)(2.65) S = 0. 423 = 42. 3%
