About this test
Enter the test readings to get the coefficient of permeability and how permeable the soil is.
How it's calculated
- Constant head: k = QL/(Aht)
- Falling head: k = (aL/At)·ln(h1/h2)
Results are calculated from the values you enter using standard formulas. Download the PDF to keep a record. For certified testing, design or construction, talk to our engineers.
