Dry Unit Weight given Percentage of Air Voids Solution

STEP 0: Pre-Calculation Summary

Formula Used

Dry Unit Weight = (1-Percentage of Air Voids)*Specific Gravity of Soil*Unit Weight of Water/(1+Water Content of Soil from Pycnometer*Specific Gravity of Soil)
γ_dry = (1-n_a)*G_s*γ_water/(1+w_s*G_s)
This formula uses 5 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.
Percentage of Air Voids - Percentage of Air Voids in the soil is obtained by dividing the volume of air to the total volume.
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.
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.

STEP 1: Convert Input(s) to Base Unit

Percentage of Air Voids: 0.2 --> No Conversion Required
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)
Water Content of Soil from Pycnometer: 8.3 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

γ_dry = (1-n_a)*G_s*γ_water/(1+w_s*G_s) --> (1-0.2)*2.65*9810/(1+8.3*2.65)

Evaluating ... ...

γ_dry = 904.422700587084

STEP 3: Convert Result to Output's Unit

904.422700587084 Newton per Cubic Meter -->0.904422700587084 Kilonewton per Cubic Meter (Check conversion here)

FINAL ANSWER

0.904422700587084 ≈ 0.904423 Kilonewton per Cubic Meter <-- Dry Unit Weight
