1. What is Specific Volume of Water?

Specific volume is the volume occupied by a unit mass of water. It's 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:

• Density of Water — Mass per unit volume (kg/m³)

Explanation: The specific volume indicates how much space 1 kilogram of water occupies at a given density.

3. Importance of Specific Volume Calculation

Details: Specific volume is crucial in engineering applications, particularly in thermodynamics for calculating work done by fluids and in designing hydraulic systems.

4. Using the Calculator

Tips: Enter the density of water in kg/m³. The value must be greater than zero. For pure water at 4°C, the density is approximately 1000 kg/m³.

5. Frequently Asked Questions (FAQ)

Q1: What is the specific volume of water at 4°C?
A: At 4°C where water has its maximum density (1000 kg/m³), the specific volume is 0.001 m³/kg.

Q2: How does temperature affect specific volume?
A: As temperature increases, water density decreases (except between 0-4°C), so specific volume increases.

Q3: What are typical units for specific volume?
A: The SI unit is m³/kg, but cm³/g and ft³/lb are also used.

Q4: Why is specific volume important in thermodynamics?
A: It's a fundamental property used in equations of state and in calculating work done by expanding fluids.

Q5: How does pressure affect specific volume of water?
A: Increased pressure generally decreases specific volume (increases density), though water is relatively incompressible.
