γ_dry = (1-n)*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 in Soil - Percentage of Air Voids in Soil is obtained by dividing the volume of air to the total volume.
Specific Gravity of Soil - Specific Gravity of Soil is an important property of soil being related to density.
Unit Weight of Water - (Measured in Newton per Cubic Meter) - Unit Weight of Water is mass per unit 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 in Soil: 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: 0.61 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

γ_dry = (1-n)*G_s*γ_water/(1+w_s*G_s) --> (1-0.2)*2.65*9810/(1+0.61*2.65)

Evaluating ... ...

γ_dry = 7948.48079495509

STEP 3: Convert Result to Output's Unit

7948.48079495509 Newton per Cubic Meter -->7.94848079495509 Kilonewton per Cubic Meter (Check conversion here)

FINAL ANSWER

7.94848079495509 ≈ 7.948481 Kilonewton per Cubic Meter <-- Dry Unit Weight
