## Percentage of air voids when dry unit weight in terms of percentage of air voids is given Solution

STEP 0: Pre-Calculation Summary
Formula Used
percentage_of_air_voids = 1-(Dry unit weight of soil*(1+water content*Specific gravity of the soil)/Specific gravity of the soil*Unit weight of water)
na = 1-(γd*(1+w*Gs)/Gs*γw)
This formula uses 4 Variables
Variables Used
Dry unit weight of soil - The dry unit weight of soil is the weight of soil solids per unit of total volume of soil mass. (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.
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)
STEP 1: Convert Input(s) to Base Unit
Dry unit weight of soil: 100 Kilonewton per Cubic Meter --> 0.1 Newton per Cubic Meter (Check conversion here)
water content: 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)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
na = 1-(γd*(1+w*Gs)/Gs*γw) --> 1-(0.1*(1+1*2.65)/2.65*0.009807)
Evaluating ... ...
na = 0.998649224528302
STEP 3: Convert Result to Output's Unit
0.998649224528302 --> No Conversion Required
0.998649224528302 <-- percentage of air voids
(Calculation completed in 00.007 seconds)
