1. What is Specific Volume?

Specific Volume of a substance is its volume per unit mass. It is the reciprocal of density and represents how much space one kilogram of the material occupies.

2. How Does the Calculator Work?

The calculator uses the specific volume formula:

Where:

• \( v \) — Specific Volume (m³/kg)
• \( \rho \) — Density (kg/m³)

Explanation: The formula calculates the volume occupied by one unit mass of a substance, which is the inverse of its density.

3. Importance of Specific Volume Calculation

Details: Specific volume is important in thermodynamics, fluid mechanics, and material science for characterizing substances and their behavior under different conditions.

4. Using the Calculator

Tips: Enter density in kg/m³. The value must be valid (density > 0).

5. Frequently Asked Questions (FAQ)

Q1: What is the relationship between specific volume and density?
A: Specific volume and density are reciprocals of each other. Specific volume = 1/density.

Q2: What are typical specific volume values?
A: Specific volume values vary widely depending on the material. For water at 4°C, specific volume is approximately 0.001 m³/kg, while for air at room temperature it's about 0.833 m³/kg.

Q3: Why is specific volume important in thermodynamics?
A: Specific volume is a fundamental property used in equations of state and in analyzing thermodynamic processes involving gases and liquids.

Q4: How does temperature affect specific volume?
A: For most substances, specific volume increases with temperature as materials typically expand when heated.

Q5: Can specific volume be used for gases and liquids?
A: Yes, specific volume applies to all states of matter, though the values differ significantly between gases, liquids, and solids.
