1. What is the Cylinder Volume Formula?

The cylinder volume formula calculates the capacity of a cylindrical tank in gallons using diameter and height measurements. This is particularly useful in engineering, manufacturing, and liquid storage applications.

2. How Does the Calculator Work?

The calculator uses the cylinder volume formula:

Where:

• \( V \) — Volume in gallons
• \( d \) — Diameter in inches
• \( h \) — Height in inches
• \( \pi \) — Mathematical constant (~3.14159)
• 231 — Cubic inches per gallon conversion factor

Explanation: The formula calculates the cylindrical volume in cubic inches (πr²h) then converts to gallons by dividing by 231 cubic inches per gallon.

3. Importance of Volume Calculation

Details: Accurate volume calculation is essential for determining tank capacities, liquid storage requirements, and industrial process design.

4. Using the Calculator

Tips: Enter diameter and height in inches. Both values must be positive numbers. The result will be the volume in US gallons.

5. Frequently Asked Questions (FAQ)

Q1: Why divide by 231?
A: 231 cubic inches equals 1 US gallon, which is the standard conversion factor.

Q2: Can I use this for metric measurements?
A: No, this calculator is specifically for inches to US gallons. For metric, use centimeters and liters (1 liter = 1000 cm³).

Q3: How accurate is this calculation?
A: The calculation is mathematically precise. Any inaccuracy would come from measurement errors in diameter or height.

Q4: Does this work for oval or irregular tanks?
A: No, this formula is only for perfect cylinders. Different formulas are needed for other shapes.

Q5: What about tank wall thickness?
A: This calculates internal volume. For external measurements, subtract twice the wall thickness from diameter and height.
