Relative Density of Cohesionless Soil given Unit Weight of Soil Solution

STEP 0: Pre-Calculation Summary

Formula Used

Relative Density in Soil Mechanics = ((1/Minimum Unit Weight)-(1/Dry Unit Weight))/((1/Minimum Unit Weight)-(1/Maximum Unit Weight))
R_D = ((1/γ_min)-(1/γ_dry))/((1/γ_min)-(1/γ_max))
This formula uses 4 Variables

Variables Used

Relative Density in Soil Mechanics - Relative Density in Soil Mechanics is density of an object in terms of the density of another reference object.
Minimum Unit Weight - (Measured in Kilonewton per Cubic Meter) - Minimum Unit Weight of soil is ratio of weight of soil to maximum volume of soil.
Dry Unit Weight - (Measured in Kilonewton per Cubic Meter) - Dry Unit Weight of soil is the weight of soil solids per unit of total volume of soil mass.
Maximum Unit Weight - (Measured in Kilonewton per Cubic Meter) - Maximum Unit Weight of soil is ratio of weight of soil to minimum volume of soil.

STEP 1: Convert Input(s) to Base Unit

Minimum Unit Weight: 5 Kilonewton per Cubic Meter --> 5 Kilonewton per Cubic Meter No Conversion Required
Dry Unit Weight: 6.12 Kilonewton per Cubic Meter --> 6.12 Kilonewton per Cubic Meter No Conversion Required
Maximum Unit Weight: 10 Kilonewton per Cubic Meter --> 10 Kilonewton per Cubic Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

R_D = ((1/γ_min)-(1/γ_dry))/((1/γ_min)-(1/γ_max)) --> ((1/5)-(1/6.12))/((1/5)-(1/10))

Evaluating ... ...

R_D = 0.366013071895425

STEP 3: Convert Result to Output's Unit

0.366013071895425 --> No Conversion Required

FINAL ANSWER

0.366013071895425 ≈ 0.366013 <-- Relative Density in Soil Mechanics
