Mass of Solids Formula:
Definition: This calculator determines the mass of solid particles in soil based on the mass of water and the water content percentage.
Purpose: It helps geotechnical engineers and soil scientists analyze soil composition and properties.
The calculator uses the formula:
Where:
Explanation: The mass of water is multiplied by (water content - 1) to determine the mass of solid particles in the soil sample.
Details: Knowing the mass of solids is crucial for determining soil density, porosity, and other geotechnical properties important for construction and agriculture.
Tips: Enter the mass of water in kg and water content as a percentage. Both values must be positive numbers.
Q1: Why subtract 1 from water content?
A: The subtraction accounts for the ratio between water mass and solid mass in the soil composition.
Q2: What's a typical water content range for soils?
A: Water content can range from 5% for dry soils to over 100% for organic soils and clays.
Q3: How do I measure mass of water in soil?
A: Typically by weighing a soil sample before and after oven-drying at 105°C for 24 hours.
Q4: Can this be used for other materials?
A: Yes, the same principle applies to any water-solid mixture, though interpretation may vary.
Q5: Why is the result sometimes negative?
A: Negative values indicate water content less than 100%, which is normal for most soils.
