Saturated Unit Weight Of Soil Calculator

How to calculate the saturated unit weight of soil? Enter the total weight of dry soil, total weight of moisture, and total volume of wet soil into the following calculator, Just fill in the values, and the calculator will give you the answer.

What Is Saturated Unit Weight of Soil?

The saturated unit weight of soil is the weight of soil when it is fully saturated with water, it mean all the voids in the soil are filled with water. It is an essential parameter in geotechnical engineering, as it helps to understand the behavior of soil under wet conditions. The saturated unit weight is higher than the dry unit weight because of the added water content.

How to Use the Calculator

This calculator has both basic and advanced functionalities. Here’s how you can use it:

1. Basic Calculator:

1. Total Weight of Dry Soil (g): Enter the total weight of the dry soil sample in grams. For example, input 1200 grams.
2. Total Weight of Moisture (g): Enter the total weight of the moisture in grams. For example, input 300 grams.
3. Total Volume of Wet Soil (cm³): Enter the total volume of the wet soil in cubic centimeters. For example, input 1000 cm³.
4. Saturated Unit Weight of Soil (g/cm³): If you want to calculate this value, leave it blank, and the calculator will find it for you.

Example 1:

• Enter 1200 grams for the dry soil weight.
• Enter 300 grams for the moisture weight.
• Enter 1000 cm³ for the volume of wet soil.
• The calculator will compute the saturated unit weight, giving you 1.5 g/cm³.

2. Advanced Calculator:

In the advanced mode, you can calculate the dry unit weight of soil using different parameters.

1. Weight of Soil After Drying (g): Enter the weight of the soil after drying in grams. For example, input 1000 grams.
2. Initial Weight of Wet Soil (g): Enter the initial weight of the wet soil in grams. For example, input 1200 grams.
3. Volume of Soil Sample (cm³): Enter the volume of the soil sample in cubic centimeters. For example, input 800 cm³.
4. Moisture Content (%): Enter the moisture content as a percentage. For example, input 25%.

Example 1:

• Enter 1000 grams for the weight of the soil after drying.
• Enter 1200 grams for the initial weight of wet soil.
• Enter 800 cm³ for the volume of the soil sample.
• Enter 25% for the moisture content.
• The calculator will compute the dry unit weight of soil, giving you 1.25 g/cm³.

Formula

To calculate the saturated unit weight of soil, use the following formula:

$$Y = \frac{{WDS + WM}}{V}$$

Variables

How To Calculate Unit Weight Of Soil

Example 1:

Given:

• Total Weight of Dry Soil (WDS) = 1200 g
• Total Weight of Moisture (WM) = 300 g
• Total Volume of Wet Soil (V) = 1000 cm³

Step 1: Add dry soil weight and moisture weight:

$1200 + 300 = 1500$

grams.

Step 2: Divide by the volume:

$1500 / 1000 = 1.5$

g/cm³.

So, the saturated unit weight of the soil is 1.5 g/cm³.

Example 2:

Given:

• Total Weight of Dry Soil (WDS) = 800 g
• Total Weight of Moisture (WM) = 200 g
• Total Volume of Wet Soil (V) = 700 cm³

Step 1: Add dry soil weight and moisture weight:

$800 + 200 = 1000$

grams.

Step 2: Divide by the volume:

$1000 / 700 = 1.43$

g/cm³.

So, the saturated unit weight of the soil is 1.43 g/cm³.

Final Words

This Soil Calculator makes it easy to find the saturated soil weight. You just enter a few values and it does the math for you. Figuring saturated unit weight can help with soil testing.
