1. What is Cylinder Liquid Volume?

The volume of liquid in a cylinder is the amount of space occupied by the liquid. This calculator computes the volume in gallons for a cylindrical container based on its radius and height.

2. How Does the Calculator Work?

The calculator uses the cylinder volume formula:

Where:

• \( V \) — Volume in gallons
• \( r \) — Radius of the cylinder in inches
• \( h \) — Height of the cylinder in inches
• 231 — Conversion factor (cubic inches to gallons)

Explanation: The formula calculates the volume in cubic inches first (πr²h) then converts to gallons by dividing by 231 (since 1 gallon = 231 cubic inches).

3. Importance of Volume Calculation

Details: Accurate volume calculation is crucial for liquid storage, chemical processing, fuel management, and various industrial applications where precise measurements are required.

4. Using the Calculator

Tips: Enter radius and height in inches. Both values must be positive numbers. The calculator will compute the volume in gallons.

5. Frequently Asked Questions (FAQ)

Q1: Why divide by 231?
A: There are 231 cubic inches in one US liquid gallon, which is the standard conversion factor.

Q2: Can I use this for metric measurements?
A: No, this calculator is specifically for inches to gallons. For metric, you would use different units (cm or m to liters).

Q3: Does this work for partially filled cylinders?
A: Yes, as long as you use the actual liquid height (not the full cylinder height) for the calculation.

Q4: How accurate is this calculation?
A: It's mathematically precise for perfect cylinders. Real-world tanks may have slight variations due to manufacturing tolerances.

Q5: What about non-vertical cylinders?
A: This calculator assumes the cylinder is vertical. Horizontal cylinders require more complex calculations.
