## Dry unit weight in terms of percentage of air voids Solution

STEP 0: Pre-Calculation Summary
Formula Used
dry_unit_weight_of_soil = (1-percentage of air voids)*Specific gravity of the soil*Unit weight of water/(1+water content*Specific gravity of the soil)
γd = (1-na)*Gs*γw/(1+w*Gs)
This formula uses 4 Variables
Variables Used
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 the soil- Specific gravity of the soil is an important property of soil being related to density.
Unit weight of water - Unit weight of water is the weight of watet per unit volume of a water. (Measured in Kilonewton per Cubic Meter)
water content- Water content is the ratio of the weight of water to the weight of solids present in the soil.
STEP 1: Convert Input(s) to Base Unit
percentage of air voids: 1 --> No Conversion Required
Specific gravity of the soil: 2.65 --> No Conversion Required
Unit weight of water: 9.807 Kilonewton per Cubic Meter --> 0.009807 Newton per Cubic Meter (Check conversion here)
water content: 1 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
γd = (1-na)*Gs*γw/(1+w*Gs) --> (1-1)*2.65*0.009807/(1+1*2.65)
Evaluating ... ...
γd = 0
STEP 3: Convert Result to Output's Unit
0 Newton per Cubic Meter -->0 Kilonewton per Cubic Meter (Check conversion here)
FINAL ANSWER
0 Kilonewton per Cubic Meter <-- Dry unit weight of soil
(Calculation completed in 00.016 seconds)
