Variables Used
Water Content of Soil from Pycnometer - Water Content of Soil from Pycnometer is the ratio of the weight of water to the weight of the solids in a given mass of soil.
Weight of Empty Pycnometer and Moist Soil - (Measured in Gram) - Weight of Empty Pycnometer and Moist Soil is the initial mass of a container, and moist soil refers to soil containing both water and solid particles, typically measured for density calculations.
Weight of Empty Pycnometer - (Measured in Gram) - The Weight of Empty Pycnometer is the weight of pycnometer only.
Weight of Empty Pycnometer, Soil and Water - (Measured in Gram) - Weight of Empty Pycnometer, Soil and Water is the initial mass of a container used to measure soil density, including soil and water, in geotechnical testing.
Weight of Empty Pycnometer and Water - (Measured in Gram) - Weight of Empty Pycnometer and Water is its mass when it contains no substance, and the mass of water in a container is typically measured in grams or kilograms.
Specific Gravity of Soil Solids - Specific Gravity of Soil Solids is defined as the weight of soil solids to weight of equal volume of water.
STEP 1: Convert Input(s) to Base Unit
Weight of Empty Pycnometer and Moist Soil: 800 Gram --> 800 Gram No Conversion Required
Weight of Empty Pycnometer: 125 Gram --> 125 Gram No Conversion Required
Weight of Empty Pycnometer, Soil and Water: 1000 Gram --> 1000 Gram No Conversion Required
Weight of Empty Pycnometer and Water: 650 Gram --> 650 Gram No Conversion Required
Specific Gravity of Soil Solids: 2.64 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
ws = ((((w2-w1)/(w3-w4))*((G-1)/G))-1) --> ((((800-125)/(1000-650))*((2.64-1)/2.64))-1)
Evaluating ... ...
ws = 0.198051948051948
STEP 3: Convert Result to Output's Unit
0.198051948051948 --> No Conversion Required
FINAL ANSWER
0.198051948051948 0.198052 <-- Water Content of Soil from Pycnometer

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.

How to Calculate Water Content of Soil from Pycnometer?
