1. What is the Well Volume Formula?

The well volume formula calculates the volume of a cylindrical well in gallons using the equation: Volume = π × r² × h × 7.48. This formula accounts for the conversion from cubic feet to gallons (1 cubic foot = 7.48 gallons).

2. How Does the Calculator Work?

The calculator uses the well volume formula:

Where:

• \( \pi \) — Mathematical constant (approximately 3.14159)
• \( r \) — Radius of the well in feet
• \( h \) — Height/depth of the well in feet
• 7.48 — Conversion factor from cubic feet to gallons

Explanation: The formula calculates the cylindrical volume (πr²h) in cubic feet and then converts it to gallons by multiplying by 7.48.

3. Importance of Well Volume Calculation

Details: Accurate well volume calculation is essential for water management, treatment chemical dosing, pump sizing, and determining water storage capacity in well systems.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why multiply by 7.48 in the formula?
A: The factor 7.48 converts cubic feet to gallons, as 1 cubic foot equals 7.48 US gallons.

Q2: What if my well isn't perfectly cylindrical?
A: This formula assumes a perfect cylinder. For irregular shapes, more complex calculations or measurements may be needed.

Q3: Can I use different units of measurement?
A: The calculator is designed for feet. If using other units, convert them to feet first or adjust the conversion factor accordingly.

Q4: How accurate is this calculation?
A: The calculation is mathematically precise for perfect cylinders. Actual well volume may vary due to well construction and irregularities.

Q5: What's the practical application of well volume calculation?
A: Used for determining water capacity, calculating treatment chemical requirements, designing pumping systems, and well maintenance planning.
