1. What is the Cylindrical Tank Volume Formula?

The formula calculates the volume of a cylindrical tank in US gallons based on the tank's dimensions in inches. It's commonly used in industrial, agricultural, and domestic applications for liquid storage.

2. How Does the Calculator Work?

The calculator uses the cylindrical volume formula:

Where:

• \( \pi \) — Mathematical constant (~3.14159)
• \( r \) — Radius of the tank (inches)
• \( h \) — Height of the tank (inches)
• 231 — Conversion factor (cubic inches to US gallons)

Explanation: The formula calculates the volume in cubic inches first (πr²h), then converts to US gallons by dividing by 231 (since 1 US gallon = 231 cubic inches).

3. Importance of Tank Volume Calculation

Details: Accurate volume calculation is essential for determining storage capacity, planning liquid quantities, and ensuring proper tank sizing for various applications.

4. Using the Calculator

Tips: Measure the radius and height of your cylindrical tank in inches. Enter these values in the calculator. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why divide by 231 in the formula?
A: 231 cubic inches equals 1 US gallon, so this conversion factor gives the volume in US gallons.

Q2: Can I use this for non-cylindrical tanks?
A: No, this formula is specific to perfect cylinders. Other shapes require different formulas.

Q3: How accurate is this calculation?
A: It's mathematically precise for perfect cylinders. Real-world tanks may vary slightly due to manufacturing tolerances.

Q4: What if my measurements are in feet?
A: Convert feet to inches first (1 foot = 12 inches) before using the calculator.

Q5: Can this be used for imperial gallons?
A: No, this calculates US gallons. For imperial gallons (UK), you would divide by 277.42 instead of 231.
