1. What is Density Calculation?

The density calculation converts relative density (specific gravity) to absolute density using the density of water as a reference. This is particularly useful in fluid mechanics and material science applications.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Relative\ Density \) — Dimensionless ratio of substance density to water density
• \( Density\ of\ Water \) — Typically 1000 kg/m³ at 4°C

Explanation: The relative density (specific gravity) is multiplied by the reference density of water to obtain the absolute density of the substance.

3. Importance of Density Calculation

Details: Accurate density values are essential for buoyancy calculations, material characterization, quality control, and various engineering applications.

4. Using the Calculator

Tips: Enter the relative density (unitless) and the density of water (typically 1000 kg/m³ at 4°C). The calculator will output the absolute density in kg/m³.

5. Frequently Asked Questions (FAQ)

Q1: What is relative density?
A: Relative density (specific gravity) is the ratio of a substance's density to the density of water at a specified temperature.

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

Q3: How does temperature affect the calculation?
A: Both relative density and water density values should be for the same temperature to get accurate results.

Q4: Can I use this for other reference liquids?
A: Yes, if you substitute the density of the reference liquid instead of water, the calculation works the same way.

Q5: What are common applications of this calculation?
A: Used in brewing, petroleum industry, chemical processing, and any field where specific gravity measurements need conversion to absolute density.
