In conducting a sand cone test, you determine the wet density of the soil taken from the hole is 130.7 lb/ft3. The moisture content of the soil is 12.6 percent. What is the dry density of the soil taken from the hole to one decimal place?
Understand the Problem
The question is asking us to calculate the dry density of the soil based on the given wet density and moisture content. To find the dry density, we can use the formula: Dry Density = Wet Density / (1 + Moisture Content), where the moisture content is expressed as a decimal.
Answer
The dry density calculation is defined as $ \text{Dry Density} = \frac{\text{Wet Density}}{1 + \text{Moisture Content}} $.
Answer for screen readers
The final answer for the dry density calculation is dependent on the specific values of wet density and moisture content provided.
Steps to Solve
- Convert Moisture Content to Decimal
To use the formula, first ensure that the moisture content is expressed as a decimal. If the moisture content is given in percentage, divide it by 100.
- Write the Formula for Dry Density
The formula to calculate dry density is given by:
$$ \text{Dry Density} = \frac{\text{Wet Density}}{1 + \text{Moisture Content}} $$
- Substitute Known Values into the Formula
Insert the values for wet density and moisture content (in decimal form) into the formula.
- Perform the Calculation
Calculate the right side of the equation to get the dry density.
- Round if Necessary
If required, round the dry density to the appropriate number of decimal places based on the context of your problem.
The final answer for the dry density calculation is dependent on the specific values of wet density and moisture content provided.
More Information
Understanding how moisture content affects soil density is crucial in various fields such as civil engineering and agriculture. The dry density of soil is particularly important for construction and soil management practices.
Tips
- Forgetting to convert the moisture content percentage into a decimal.
- Mixing up the wet density and dry density values in the equation.
- Misapplying the formula, especially the structure of the denominator.
