1. What is SG Density Calculation?

The SG (Specific Gravity) Density calculation determines the density of a substance by multiplying its specific gravity with the reference density of water. This is commonly used in various scientific and engineering applications.

2. How Does the Calculator Work?

The calculator uses the density formula:

Where:

• \( \rho \) — Density of the substance (kg/m³)
• \( SG \) — Specific Gravity of the substance (dimensionless)
• \( \rho_{water} \) — Density of reference water (typically 1000 kg/m³ at 4°C)

Explanation: Specific Gravity is the ratio of a substance's density to the density of water, making this a straightforward multiplication.

3. Importance of Density Calculation

Details: Density calculations are fundamental in material science, fluid mechanics, buoyancy calculations, and quality control processes.

4. Using the Calculator

Tips: Enter the specific gravity of your substance and the reference water density (default is 1000 kg/m³). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is specific gravity?
A: Specific gravity is a dimensionless quantity that compares the density of a substance to the density of water at a specified temperature.

Q2: Why is water density typically 1000 kg/m³?
A: Pure water has a density of 1000 kg/m³ at 4°C, which is its maximum density point.

Q3: Can I use different reference densities?
A: Yes, you can adjust the water density value if working with different reference conditions or temperatures.

Q4: What are common SG values?
A: Most liquids range from 0.8 (light oils) to 1.5 (heavy brines). Water has SG = 1 by definition.

Q5: How does temperature affect this calculation?
A: Both SG and reference density are temperature-dependent, so ensure values are for the same temperature.
