1. What is a Fuel Tank Size Calculator?

Definition: This calculator estimates the volume capacity of fuel tanks based on their dimensions, supporting both rectangular and cylindrical shapes.

Purpose: It helps engineers, mechanics, and vehicle owners determine the storage capacity of fuel tanks for proper fuel management and system design.

2. How Does the Calculator Work?

The calculator uses different formulas based on tank shape:

Where:

• For rectangular tanks:
  • \( L \) — Length
  • \( W \) — Width
  • \( H \) — Height
• For cylindrical tanks:
  • \( r \) — Radius
  • \( h \) — Height
• \( V \) — Volume (cubic units)

3. Importance of Fuel Tank Volume Calculation

Details: Accurate volume calculation ensures proper fuel system design, helps determine range/endurance, and assists in compliance with safety regulations.

4. Using the Calculator

Tips:

1. Select tank shape (rectangular or cylindrical)
2. Enter all required dimensions (must be > 0)
3. All measurements should be in the same units
4. For cylindrical tanks, diameter can be entered as radius × 2

5. Frequently Asked Questions (FAQ)

Q1: What units should I use?
A: Any consistent units (inches, feet, cm, meters). The result will be in cubic units of your input.

Q2: How do I calculate gallons/liters from cubic units?
A: Multiply cubic inches by 0.004329 for US gallons, cubic feet by 7.48052 for US gallons, or cubic meters by 1000 for liters.

Q3: Does this account for tank thickness?
A: No, this calculates internal volume. For external dimensions, subtract wall thickness from measurements.

Q4: How accurate is this for irregularly shaped tanks?
A: This works best for regular shapes. For complex shapes, consider using multiple sections or fluid displacement methods.

Q5: Can I calculate fuel weight from this?
A: Yes, multiply volume by fuel density (approximately 6.7 lb/gal for diesel, 6.0 lb/gal for gasoline).
