Porosity given Saturated Unit Weight in Porosity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Porosity of Soil = (Saturated Unit Weight-(Specific Gravity of Soil Solids*Unit Weight of Water in Soil Mechanics))/Unit Weight of Water in Soil Mechanics*(1-Specific Gravity of Soil Solids)
η_s = (γ_sat-(G*γ_w))/γ_w*(1-G)
This formula uses 4 Variables

Variables Used

Porosity of Soil - Porosity of Soil is the ratio of the volume of voids to the volume of soil.
Saturated Unit Weight - (Measured in Newton per Cubic Meter) - Saturated Unit Weight is the value of the unit weight of the soil when the soil is completely saturated with water that is all the soil pores are completely filled with water.
Specific Gravity of Soil Solids - Specific Gravity of Soil Solids is defined as the weight of soil solids to weight of equal volume of water.
Unit Weight of Water in Soil Mechanics - (Measured in Newton per Cubic Meter) - Unit Weight of Water in Soil Mechanics is the weight per unit volume of water.

STEP 1: Convert Input(s) to Base Unit

Saturated Unit Weight: 17854 Newton per Cubic Meter --> 17854 Newton per Cubic Meter No Conversion Required
Specific Gravity of Soil Solids: 2.64 --> No Conversion Required
Unit Weight of Water in Soil Mechanics: 9810 Newton per Cubic Meter --> 9810 Newton per Cubic Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

η_s = (γ_sat-(G*γ_w))/γ_w*(1-G) --> (17854-(2.64*9810))/9810*(1-2.64)

Evaluating ... ...

η_s = 1.34483343527013

STEP 3: Convert Result to Output's Unit

1.34483343527013 --> No Conversion Required

FINAL ANSWER

1.34483343527013 ≈ 1.344833 <-- Porosity of Soil

Total Volume of Soil given Porosity of Soil Sample

Go Volume of Soil Sample = (Volume of Voids in Soil Mechanics/Porosity Volume Percent)*100

Volume of Voids Porosity of Soil Sample

Go Volume of Voids in Soil Mechanics = (Porosity Volume Percent*Volume of Soil Sample)/100

Porosity of Soil Sample

Go Porosity in Soil Mechanics = Volume of Voids in Soil Mechanics/Volume of Soil Sample

Porosity given Void Ratio

Go Porosity in Soil Mechanics = Void Ratio/(1+Void Ratio)
