1. What is a Tank Volume Calculator Gallons per Inch?

Definition: This calculator determines how many gallons of liquid a tank holds per inch of height, for either rectangular or cylindrical tanks.

Purpose: It helps in liquid storage planning, chemical dosing, and understanding tank capacity at different levels.

2. How Does the Calculator Work?

The calculator uses different formulas based on tank shape:

\[ V_{gal/in} = \frac{L \times W}{231} \text{ (rectangular)} \] \[ V_{gal/in} = \frac{\pi \times r^2}{231} \text{ (cylindrical)} \]

Where:

\( V_{gal/in} \) — Gallons per inch of height
\( L \) — Length of rectangular tank (inches)
\( W \) — Width of rectangular tank (inches)
\( r \) — Radius of cylindrical tank (inches)
231 — Cubic inches per gallon conversion factor

Explanation: The formulas calculate the cross-sectional area of the tank divided by 231 (cubic inches per gallon).

3. Importance of Gallons per Inch Calculation

Details: Knowing gallons per inch helps in precise liquid level monitoring, inventory management, and process control in industrial and agricultural applications.

4. Using the Calculator

Tips: Select tank shape, then enter either length/width for rectangular tanks or radius for cylindrical tanks. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why 231 cubic inches per gallon?
A: This is the standard US gallon volume (231 cubic inches = 1 US liquid gallon).

Q2: Can I use this for irregularly shaped tanks?
A: No, this calculator only works for regular rectangular or cylindrical shapes.

Q3: How do I calculate total tank capacity?
A: Multiply gallons per inch by the total height of your tank.

Q4: Does this account for tank thickness or internal structures?
A: No, this calculates theoretical volume. Actual capacity may be slightly less.

Q5: Can I use feet instead of inches?
A: No, the formula requires inches since the gallon conversion is based on cubic inches.
