Water Content given Dry Unit Weight at Full Saturation Solution

STEP 0: Pre-Calculation Summary

Formula Used

Water Content = ((Specific Gravity of Soil*Unit Weight of Water/Dry Unit Weight)-1)/Specific Gravity of Soil
ω = ((G_s*γ_water/γ_dry)-1)/G_s
This formula uses 4 Variables

Variables Used

Water Content - Water Content is the ratio of the weight of water to the weight of dry soil.
Specific Gravity of Soil - Specific Gravity of Soil is defined as the ratio of the weight of a given volume of soil solids to the weight of an equal volume of water at a specified temperature (usually 4°C).
Unit Weight of Water - (Measured in Newton per Cubic Meter) - Unit Weight of Water is the weight per unit volume of water.
Dry Unit Weight - (Measured in Newton per Cubic Meter) - Dry Unit Weight of soil is the weight of soil solids per unit of total volume of soil mass.

STEP 1: Convert Input(s) to Base Unit

Specific Gravity of Soil: 2.65 --> No Conversion Required
Unit Weight of Water: 9.81 Kilonewton per Cubic Meter --> 9810 Newton per Cubic Meter (Check conversion here)
Dry Unit Weight: 6.12 Kilonewton per Cubic Meter --> 6120 Newton per Cubic Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

ω = ((G_s*γ_water/γ_dry)-1)/G_s --> ((2.65*9810/6120)-1)/2.65

Evaluating ... ...

ω = 1.22558268590455

STEP 3: Convert Result to Output's Unit

1.22558268590455 --> No Conversion Required

FINAL ANSWER

1.22558268590455 ≈ 1.225583 <-- Water Content

< Water Content and Volume of Solids in Soil Calculators

Total Mass of Soil

Go Total Mass of Sand in Soil Mechanics = (Water Content of Soil from Pycnometer*Weight of Solids in Soil Mechanics/100)+Weight of Solids in Soil Mechanics

Mass of Water given Water Content with respect to Mass of Water

Go Weight of Water in Soil Mechanics = Water Content of Soil from Pycnometer*Weight of Solids in Soil Mechanics/100

Dry Mass given Water Content with respect to Mass of Water

Go Weight of Solids in Soil Mechanics = Weight of Water in Soil Mechanics*100/Water Content of Soil from Pycnometer

Volume of Solids given Density of Solids

Go Volume of Solids in Soil = Weight of Solids in Soil Mechanics/Dry Density

Water Content given Dry Unit Weight at Full Saturation Formula

Water Content = ((Specific Gravity of Soil*Unit Weight of Water/Dry Unit Weight)-1)/Specific Gravity of Soil
ω = ((G_s*γ_water/γ_dry)-1)/G_s

What is Saturation?

Saturation is the degree or extent to which something is dissolved or absorbed compared with the maximum possible, usually expressed as a percentage.
