Water Content of Soil from Pycnometer Formula

What is the Pycnometer method of determining Soil Water content?

The pycnometer method is a rapid method of water content determination for soils whose specific gravity is accurately known. The method is suitable for coarse-grained soils only as the entrapped air is likely to cause a significant error in water content determination for fine-grained soils.

What are the various methods for determination of water content of soil?

1. Oven-Drying Method 2. Sand Bath Method 3. Alcohol Method 4. Infrared Lamp Torsion Balance Method 5. Calcium Carbide Method 6. Pycnometer Method.
