Dry Unit Weight given Bulk Unit Weight and Degree of Saturation Solution

STEP 0: Pre-Calculation Summary

Formula Used

Dry Unit Weight = (Bulk Unit Weight-(Degree of Saturation*Saturated Unit Weight of Soil))/(1-Degree of Saturation)
γ_dry = (γ_bulk-(S*γ_saturated))/(1-S)
This formula uses 4 Variables

Variables Used

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.
Bulk Unit Weight - (Measured in Newton per Cubic Meter) - Bulk Unit Weight is the weight of a unit volume of soil. It is a measure of the density of the soil when it is in its natural, undisturbed state.
Degree of Saturation - Degree of Saturation is the ratio of the volume of water to the volume of voids.
Saturated Unit Weight of Soil - (Measured in Newton per Cubic Meter) - Saturated Unit Weight of Soil is defined as the weight per unit volume of soil when it is fully saturated with water.

STEP 1: Convert Input(s) to Base Unit

Bulk Unit Weight: 20.89 Kilonewton per Cubic Meter --> 20890 Newton per Cubic Meter (Check conversion here)
Degree of Saturation: 2.56 --> No Conversion Required
Saturated Unit Weight of Soil: 11.89 Kilonewton per Cubic Meter --> 11890 Newton per Cubic Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

γ_dry = (γ_bulk-(S*γ_saturated))/(1-S) --> (20890-(2.56*11890))/(1-2.56)

Evaluating ... ...

γ_dry = 6120.76923076923

STEP 3: Convert Result to Output's Unit

6120.76923076923 Newton per Cubic Meter -->6.12076923076923 Kilonewton per Cubic Meter (Check conversion here)

FINAL ANSWER

6.12076923076923 ≈ 6.120769 Kilonewton per Cubic Meter <-- Dry Unit Weight
