(a) Estimate the coefficient of permeability for a sand deposit where field testing indicates the in-place void ratio is about 0.50, and representative laboratory grain-size analyses indicate the D₁₀
size is 0.55 mm and the uniformity coefficient C_u
is eight. (Use Fig.

10.)

(b) Apply the Kozeny-Carman equation (Equation 10c) to estimate the coefficient of permeability, then compare the result to the value obtained for (a).

(c) Using the above information, and referring to Table 2, indicate the probable soil type (soil classification).
