1. What is Specific Volume?

Specific Volume of a body is its volume per unit mass. It is the reciprocal of density and is an important property in thermodynamics and fluid mechanics.

2. How Does the Calculator Work?

The calculator uses the specific volume formula:

Where:

• \( v \) — Specific Volume (m³/kg)
• \( V_T \) — Total Volume (m³)
• \( m \) — Mass (kg)

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

3. Importance of Specific Volume Calculation

Details: Specific volume is crucial in thermodynamics for analyzing gas behavior, in fluid mechanics for flow calculations, and in various engineering applications where mass-volume relationships are important.

4. Using the Calculator

Tips: Enter volume in cubic meters (m³), mass in kilograms (kg). Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is the relationship between specific volume and density?
A: Specific volume is the reciprocal of density (v = 1/ρ). While density is mass per unit volume, specific volume is volume per unit mass.

Q2: What are typical units for specific volume?
A: The SI unit is cubic meters per kilogram (m³/kg), but other units like cubic feet per pound (ft³/lb) are also used in some systems.

Q3: Why is specific volume important in thermodynamics?
A: Specific volume is a fundamental property in thermodynamic equations of state and is particularly important when working with gases and phase changes.

Q4: How does specific volume change with temperature and pressure?
A: For gases, specific volume increases with temperature and decreases with pressure. For liquids, the changes are much smaller but still present.

Q5: Can specific volume be used for mixtures?
A: Yes, the specific volume of a mixture can be calculated using the total volume and total mass of the mixture.
