Questions 1, 5, 9, 10, 11, 12, 13
1. Clay
5. A: -0.7 + (-6.6) = -7.3 B: -3 + (-1) = -4
Since A has a lower energy, water moves from B to A.
9.
A) Pb = Ms/Vt
Volume = π (1.5 in)2(3) = 21.2 in3 = 0.0123ft3
Pb = 1.07lb/0.0123ft3 = 87.2lb/ft3
B) f = (Va+Vw) / Vt *Assume a particle density of 2.65 g/cm3
Vt – Vs = Va + Vw = 0.0123 ft3- (cm3/2.65g)(1.07lb)(453.6g/1lb)(3.53*10-5ft3/cm3) = 0.0058 ft3
f = 0.0058/0.0123 = 0.5
C) w = Mw/Ms = (1.32 – 1.07) / 1.07 = 0.23
D) θ = Vw/Vt = [0.25lb water (ft3/62.4lb)] / 0.0123 = 0.3
E) fa = Va/Vt = [0.0058 – (0.25/62.4)] / 0.0123 = 0.15
F) 0.15*( π0.252) = 0.0288 ft3 air in a 0.5 ft diameter, 1 ft long soil column.
Cross-sectional area of column = π0.252
0.0288 ft3 air / π0.252 = 0.15ft = 1.7”
10.
A)91 lb/ft3
B)0.45
C)0.098
D) 0.14
E) 0.31
F) 0.61 ft
11.
A) 1.6 g/cm3
B) 0.39
C) 0.6
D) 0.06
E)0.24
F) 0.15
12) See Excel sheet
13)
Find V of borrow material to fill in:
e = 0.75 = Va + Vw / Vs = 4285.7 yd3 / 5714.3 yd3
Therefore, 4285.7 yd3 of borrow material must be used to fill (assuming the fill contains no moisture).
For the borrow material:
e = 1.15 = 23/20 = 2292.4 yd3 / 1993.3 yd3
Ps = Ms/Vs = 150 lb/ yd3 = 4050 lb/ yd3 and w = Mw/Ms = 12%
Ms = (Ms/Vs)(Vs) = 4050lb/ yd3 * 1993.3 yd3 = 8072865 lbs = 4036 tons
Mw = (Mw/Ms)(Ms) = 0.12 * 8072865 lbs = 968744 lbs = 484 tons
