The Submerged Weight of Solids represents the effective weight of soil solids when submerged under water. It accounts for the buoyant force acting on the soil particles, providing a more accurate measure of the actual weight in submerged conditions.
The calculator uses the formula:
Where:
Explanation: This formula calculates the effective weight of soil solids when they are submerged in water, taking into account the buoyancy effect.
Details: Accurate calculation of submerged weight is crucial for geotechnical engineering applications, including foundation design, slope stability analysis, and underwater construction projects where soil is submerged.
Tips: Enter the submerged unit weight of water in kg/m³ and the total volume in m³. Both values must be positive numbers greater than zero for accurate calculation.
Q1: What is the difference between submerged weight and dry weight?
A: Submerged weight accounts for buoyancy effects when soil is underwater, while dry weight is measured in air without water saturation effects.
Q2: When is submerged weight calculation important?
A: It's essential for underwater construction, dam design, offshore structures, and any geotechnical application involving submerged soil conditions.
Q3: How does water content affect submerged weight?
A: Water content affects the unit weight of soil, which in turn influences the submerged weight calculation through the submerged unit weight parameter.
Q4: Can this formula be used for all soil types?
A: Yes, the formula is applicable to all soil types, though the submerged unit weight may vary depending on soil composition and density.
Q5: What are typical values for submerged unit weight?
A: Submerged unit weight typically ranges from 8-12 kN/m³ (approximately 815-1223 kg/m³) for most common soil types.
