1. What is a Cylinder Tank Volume Calculator?

Definition: This calculator estimates the volume of liquid a cylindrical tank can hold, measured in gallons.

Purpose: It helps engineers, tank designers, and industrial professionals determine tank capacity for storage or processing applications.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ V_{gal} = \frac{\pi \times r^2 \times h}{231} \]

Where:

\( V_{gal} \) — Volume in gallons
\( r \) — Radius of the cylinder (inches)
\( h \) — Height of the cylinder (inches)
231 — Conversion factor (cubic inches per gallon)

Explanation: The formula calculates the cylindrical volume in cubic inches then converts to gallons.

3. Importance of Tank Volume Calculation

Details: Accurate volume calculations ensure proper tank sizing for storage needs, process requirements, and safety considerations.

4. Using the Calculator

Tips: Enter the radius and height in inches. Both values must be > 0. The result shows capacity 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 diameter instead of radius?
A: Yes, just divide diameter by 2 before entering. Future versions may include diameter input.

Q3: Does this work for horizontal tanks?
A: No, this calculates volume for vertical cylindrical tanks only. Horizontal tanks require different calculations.

Q4: How accurate is this calculation?
A: It's mathematically precise for perfect cylinders. Real tanks may have variations like rounded ends or welds.

Q5: What about metric units?
A: This version uses US customary units. For liters, multiply gallons by 3.78541.
