Plastic Limit of Soil given Plasticity Index Solution

STEP 0: Pre-Calculation Summary
Formula Used
Plastic Limit = Liquid Limit-Plasticity Index
Wp = Wl-Ip
This formula uses 3 Variables
Variables Used
Plastic Limit - Plastic limit is water content at which soil changes from semi solid to plastic state.
Liquid Limit - Liquid limit is the water content of the soil that would correspond to the standard groove closing in 25 drops of the cup.
Plasticity Index - Plasticity Index is difference between liquid limit and plastic limit.
STEP 1: Convert Input(s) to Base Unit
Liquid Limit: 2.4 --> No Conversion Required
Plasticity Index: 1.2 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Wp = Wl-Ip --> 2.4-1.2
Evaluating ... ...
Wp = 1.2
STEP 3: Convert Result to Output's Unit
1.2 --> No Conversion Required
FINAL ANSWER
1.2 <-- Plastic Limit
(Calculation completed in 00.004 seconds)

Angle of Internal Friction for Soil
Go Angle of Internal Friction = arctan(Shear Force on Soil/Normal Force on Soil)
Moisture Content of Soil given Liquidity Index
Go Water Content of Soil = ((Liquidity Index*Plasticity Index)+Plastic Limit)
Plasticity Index of Soil given Liquidity Index
Go Plasticity Index = (Water Content of Soil-Plastic Limit)/Liquidity Index
Liquidity Index of Soil
Go Liquidity Index = (Water Content of Soil-Plastic Limit)/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

Plastic Limit of Soil given Plasticity Index Formula

Plastic Limit = Liquid Limit-Plasticity Index
