1. What is the Water Tank Capacity Formula?

The water tank capacity formula calculates the volume of a cylindrical tank in gallons using the tank's radius and height measurements in inches. This is essential for determining how much liquid a tank can hold.

2. How Does the Calculator Work?

The calculator uses the cylindrical volume formula:

\[ Capacity_{gallons} = \frac{\pi \times Radius_{in}^2 \times Height_{in}}{231} \]

Where:

\( Radius \) — Tank radius in inches
\( Height \) — Tank height in inches
\( \pi \) — Approximately 3.1416
231 — Conversion factor (cubic inches per gallon)

Explanation: The formula calculates the cylindrical volume in cubic inches and converts it to gallons using the standard conversion factor.

3. Importance of Capacity Calculation

Details: Accurate capacity calculation is crucial for water storage planning, industrial applications, agricultural use, and ensuring proper system sizing.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What if my tank isn't cylindrical?
A: This calculator is for cylindrical tanks only. Other shapes require different formulas.

Q2: How accurate is this calculation?
A: It's mathematically precise for perfect cylinders. Real-world tanks may vary slightly due to manufacturing tolerances.

Q3: Can I use feet instead of inches?
A: Yes, but you'll need to convert feet to inches (multiply by 12) or adjust the conversion factor accordingly.

Q4: What's the 231 conversion factor?
A: It's the number of cubic inches in one US gallon (231 in³ = 1 gallon).

Q5: Does this account for tank thickness?
A: No, this calculates internal capacity. For external dimensions, subtract wall thickness from measurements.
