1. What is the Tank Capacity Formula?

The tank capacity formula calculates the volume of a rectangular tank in gallons. It first calculates the cubic feet volume (length × width × height) then converts to gallons by multiplying by 7.48 (the number of gallons in a cubic foot).

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V \) — Volume in gallons
• \( L \) — Length in feet
• \( W \) — Width in feet
• \( H \) — Height in feet
• 7.48 — Conversion factor (gallons per cubic foot)

Explanation: The formula calculates the internal volume of a rectangular tank and converts it from cubic feet to gallons.

3. Importance of Tank Capacity Calculation

Details: Knowing tank capacity is essential for proper storage management, chemical dosing, system design, and regulatory compliance in water treatment, chemical processing, and other industries.

4. Using the Calculator

Tips: Enter dimensions in feet. Measure internal dimensions for accurate capacity. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What if my tank isn't rectangular?
A: This calculator is for rectangular tanks only. Different formulas are needed for cylindrical or other shaped tanks.

Q2: Why multiply by 7.48?
A: There are 7.48052 gallons in one cubic foot. We use 7.48 for practical calculations.

Q3: Should I use internal or external dimensions?
A: Always use internal dimensions for capacity calculations, unless you're calculating displacement.

Q4: How accurate is this calculation?
A: It's mathematically precise for perfect rectangles. Actual capacity may vary with tank shape irregularities.

Q5: Can this be used for any liquid?
A: Yes, the volume calculation is the same for any liquid, though weight will vary by density.
