Oil Tank Calculator - Volume, Capacity & Safety
Calculate oil tank volume, capacity, pressure, thermal expansion, and safety requirements. Essential for oil storage, industrial facilities, and compliance planning.
An oil tank is a container designed for storing oil and petroleum products. This calculator helps determine storage capacity, structural requirements, and safety considerations. Whether you're designing a new oil storage facility or evaluating an existing one, this tool provides comprehensive calculations for proper tank design and regulatory compliance.
Formula
Volume = πr²h
Surface Area = 2πr² + 2πrh
Oil Weight = Volume × Density × Fill%
Pressure = ρgh ÷ 1000
Thermal Expansion = Volume × 0.0007 × ΔT
Bund Volume = Tank Volume × 1.1
Where:
- r:radius (half the diameter) of the tank
- h:height of the tank
- ρ:density of the oil (typically 920 kg/m³)
- g:acceleration due to gravity (9.81 m/s²)
- ΔT:temperature change in degrees Celsius

Frequently Asked Questions
Why is thermal expansion important?
Thermal expansion in oil tanks:
1. Affects tank pressure
2. Requires adequate headspace
3. Influences safety systems
4. Impacts filling procedures
Oil expands about 0.07% per degree Celsius rise in temperature.
What is a bund and why is it needed?
A bund is a containment area that:
1. Contains potential leaks/spills
2. Must be 110% of tank volume
3. Prevents environmental contamination
4. Required by regulations
Essential for environmental protection and regulatory compliance.
How is tank pressure managed?
Tank pressure is managed through:
1. Pressure relief valves
2. Venting systems
3. Temperature control
4. Fill level monitoring
Proper pressure management is crucial for safety.
What affects flow rates?
Flow rates are influenced by:
1. Pipe diameter
2. Oil viscosity
3. Temperature
4. Pump capacity
5. System pressure
Optimal flow rates ensure efficient operations.
