Example for the Constant Head Test
For a constant head laboratory permeability test on a fine sand, the following values are given:
- Length of specimen = 10 in.
- Diameter of specimen = 2.5 in.
- Head difference = 18 in.
- Water collected in 2 minutes = 0.031 in.3
Determine:
a. Hydraulic conductivity, k, of the soil (in./min.)
b. Discharge velocity
