1. What is a Water Storage Capacity Calculator?

Definition: This calculator estimates the water storage capacity in gallons for cylindrical tanks based on their dimensions.

Purpose: It helps engineers, homeowners, and water system designers determine how much water a cylindrical tank can hold.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \text{Capacity} \) — Water volume (gallons)
• \( r \) — Radius of the tank (feet)
• \( h \) — Height of the tank (feet)
• \( 7.48 \) — Conversion factor (gallons per cubic foot)

Explanation: The formula calculates the cylindrical volume in cubic feet and converts it to gallons.

3. Importance of Water Capacity Calculation

Details: Accurate capacity calculations ensure proper system design, water supply planning, and regulatory compliance.

4. Using the Calculator

Tips: Enter the tank radius and height in feet. Both values must be > 0. The result shows capacity in gallons.

5. Frequently Asked Questions (FAQ)

Q1: Why multiply by 7.48?
A: There are 7.48052 gallons in one cubic foot of water. This converts volume from cubic feet to gallons.

Q2: Does this work for non-cylindrical tanks?
A: No, this formula is specifically for cylindrical tanks. Other shapes require different formulas.

Q3: What about tank thickness?
A: This calculates internal capacity. For external dimensions, subtract wall thickness from measurements.

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

Q5: Can I use meters instead of feet?
A: You would need to use a different conversion factor (264.172 for cubic meters to gallons).
