1. What is Gallons Per Inch Calculation?

The Gallons Per Inch calculation determines how many gallons of liquid a circular tank can hold per inch of height. This is useful for tank calibration, inventory management, and fluid measurement in cylindrical containers.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \pi \) — Mathematical constant (approximately 3.14159)
• \( r \) — Radius of the circular tank in inches
• 231 — Conversion factor (cubic inches per gallon)

Explanation: The formula calculates the cross-sectional area of the tank and converts it from cubic inches to gallons per inch of height.

3. Importance of Gallons Per Inch Calculation

Details: This calculation is essential for accurately determining liquid volumes in storage tanks, designing fluid systems, and managing inventory in industries such as petroleum, chemical processing, and water treatment.

4. Using the Calculator

Tips: Enter the radius of the circular tank in inches. The radius must be a positive value greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: Why is 231 used in the formula?
A: 231 is the conversion factor from cubic inches to US gallons (1 US gallon = 231 cubic inches).

Q2: Can this be used for oval or rectangular tanks?
A: No, this formula is specifically for circular tanks. Different formulas are needed for other shapes.

Q3: How accurate is this calculation?
A: The calculation is mathematically precise for perfect cylinders. Actual tank volumes may vary slightly due to manufacturing tolerances.

Q4: Does this work for metric measurements?
A: This calculator uses imperial units. For metric, you would need to convert measurements or use a different conversion factor.

Q5: Can I calculate total gallons if I know the height?
A: Yes, multiply the gallons per inch result by the total height in inches to get the total capacity.
