1. What is Fuel Oil Density?

Definition: Density of fuel oil is its mass per unit volume, typically measured in kilograms per cubic meter (kg/m³).

Purpose: Understanding fuel oil density is crucial for storage, transportation, and energy content calculations in the petroleum industry.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \rho = \frac{m}{V} \]

Where:

\( \rho \) — Density (kg/m³)
\( m \) — Mass (kg)
\( V \) — Volume (m³)

Explanation: The mass of fuel oil is divided by its volume to determine its density.

3. Importance of Fuel Oil Density

Details: Density affects fuel quality, energy content, and is used for volume-to-mass conversions in fuel transactions.

4. Using the Calculator

Tips: Enter the mass of fuel oil in kilograms and volume in cubic meters. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the typical density range for fuel oil?
A: Fuel oil density typically ranges from 850–950 kg/m³ depending on the specific type and temperature.

Q2: How does temperature affect fuel oil density?
A: Density decreases as temperature increases due to thermal expansion of the oil.

Q3: What are common fuel oil types and their densities?
A: No. 2 fuel oil ~ 850 kg/m³, No. 4 ~ 900 kg/m³, No. 6 ~ 950 kg/m³ (at 15°C).

Q4: Why is density important for fuel oil?
A: Density indicates energy content per unit volume and affects combustion characteristics.

Q5: How is this different from API gravity?
A: API gravity is another measure of density (141.5/(specific gravity) - 131.5), where specific gravity is relative to water.
