Physics · Permeability of Soil
Based on Allen-Hazen's experiments, the coefficient of permeability k (cm/s) is related to the effective size of soil D10 (cm) as _________ (where C is a constant with a value between 100 and 150).
- 1k = C2D10
- 2k = D10 / C2
- 3k = CD102✓
- 4k = C / D102
Correct answer
k = CD102
