1. What is Gallons Per Inch Calculation?

The Gallons Per Inch calculation determines the volume of liquid (in gallons) that corresponds to one inch of height in a cylindrical tank. This measurement is essential for tank calibration and liquid level monitoring.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( r \) — Radius of the tank (inches)
• \( \pi \) — Mathematical constant (approximately 3.14159)
• 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: Accurate gallons per inch calculation is crucial for tank calibration, inventory management, and precise liquid measurement in industrial and agricultural applications.

4. Using the Calculator

Tips: Enter the tank radius in inches. The value must be valid (radius > 0). The calculator will compute the gallons contained per inch of tank height.

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 gallon = 231 cubic inches).

Q2: Can this be used for non-cylindrical tanks?
A: No, this formula is specifically for cylindrical tanks with circular cross-sections. Other tank shapes require different calculations.

Q3: How accurate is this calculation?
A: The calculation is mathematically precise for perfect cylinders. Actual tanks may have variations due to construction tolerances.

Q4: What if my tank measurements are in different units?
A: Convert all measurements to inches before using the calculator. The result will be in gallons per inch.

Q5: Can this be used for vertical and horizontal tanks?
A: This calculation works for vertical cylindrical tanks. Horizontal tanks require more complex calculations due to the varying cross-sectional area.
