1. What is Specific Volume?

Specific volume is defined as the volume occupied per unit mass of a substance. It is the reciprocal of density and is an important thermodynamic property used in various engineering and scientific applications.

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 kilogram of a substance based on its density.

3. Importance of Specific Volume Calculation

Details: Specific volume is crucial in thermodynamics, fluid mechanics, and various engineering applications. It helps in determining the state properties of substances, particularly in the study of gases and liquids under different conditions.

4. Using the Calculator

Tips: Enter the density value in kg/m³. The value must be greater than zero to get a valid result.

5. Frequently Asked Questions (FAQ)

Q1: What is the relationship between specific volume and density?
A: Specific volume and density are inversely related. Specific volume is the reciprocal of density.

Q2: What are typical specific volume values for water?
A: At 4°C, water has a density of 1000 kg/m³, giving a specific volume of 0.001 m³/kg.

Q3: How does temperature affect specific volume?
A: As temperature increases, most substances expand, increasing their specific volume while decreasing their density.

Q4: What are the units of specific volume?
A: The SI unit is cubic meters per kilogram (m³/kg), but other units like cm³/g or ft³/lb may also be used.

Q5: Why is specific volume important in thermodynamics?
A: Specific volume is a fundamental property in thermodynamics used to define the state of a system and is essential in calculations involving work, heat transfer, and energy conversions.
