Plasticity Index of Soil given Liquidity Index Solution

STEP 0: Pre-Calculation Summary
Formula Used
Plasticity Index = (Water Content of Soil-Plastic Limit)/Liquidity Index
Ip = (w-Wp)/Il
This formula uses 4 Variables
Variables Used
Plasticity Index - Plasticity Index is difference between liquid limit and plastic limit.
Water Content of Soil - Water Content of Soil is the natural water content of soil sample.
Plastic Limit - Plastic limit is water content at which soil changes from semi solid to plastic state.
Liquidity Index - Liquidity Index is ratio of difference between moisture content and plastic limit to plasticity index.
STEP 1: Convert Input(s) to Base Unit
Water Content of Soil: 1.79 --> No Conversion Required
Plastic Limit: 1.2 --> No Conversion Required
Liquidity Index: 0.6 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Ip = (w-Wp)/Il --> (1.79-1.2)/0.6
Evaluating ... ...
Ip = 0.983333333333334
STEP 3: Convert Result to Output's Unit
0.983333333333334 --> No Conversion Required
FINAL ANSWER
0.983333333333334 0.983333 <-- Plasticity Index

Shearing Force on Plane when Sliding on Plane is Impending
Go Shear Force on Soil = (Normal Force on Soil*Coefficient of Internal Friction)
Normal Force on given Plane in Cohesionless Soil
Go Normal Force on Soil = (Shear Force on Soil/Coefficient of Internal Friction)
Coefficient of Internal Friction for Soil
Go Coefficient of Internal Friction = (Shear Force on Soil/Total Normal Force)
Percent of Soil Finer than Clay Size given Activity Index
Go Percentage of Clay Fraction = (Plasticity Index/Activity Index)
Plasticity Index of Soil given Activity Index
Go Plasticity Index = (Activity Index*Percentage of Clay Fraction)
Activity Index of Soil
Go Activity Index = (Plasticity Index/Percentage of Clay Fraction)
Shrinkage Limit of Soil given Shrinkage Index
Go Shrinkage Limit = (Plastic Limit-Shrinkage Index)
Plastic Limit of Soil given Shrinkage Index
Go Plastic Limit = (Shrinkage Index+Shrinkage Limit)
Shrinkage Index of Soil
Go Shrinkage Index = (Plastic Limit-Shrinkage Limit)
Plastic Limit of Soil given Plasticity Index
Go Plastic Limit = Liquid Limit-Plasticity Index
Liquid Limit of Soil given Plasticity Index
Go Liquid Limit = Plasticity Index+Plastic Limit
Plasticity Index of Soil
Go Plasticity Index = Liquid Limit-Plastic Limit

Plasticity Index of Soil given Liquidity Index Formula

Plasticity Index = (Water Content of Soil-Plastic Limit)/Liquidity Index
Ip = (w-Wp)/Il

What is Plasticity Index of Soil?

The plasticity index (PI) is a measure of the plasticity of the soil. The plasticity index is the size of the range of water content where the soil exhibits plastic properties. The PI is the difference between the liquid limit and the plastic limit.
