1. What is the Water Volume Calculation?

The water volume calculation determines the amount of water contained in a cylindrical well based on its radius and the depth of the water. This is essential for water management, well capacity assessment, and treatment planning.

2. How Does the Calculator Work?

The calculator uses the cylindrical volume formula:

Where:

• \( \pi \) — Mathematical constant (~3.14159)
• \( \text{Radius} \) — Distance from center to edge of well (feet)
• \( \text{Water Depth} \) — Depth of water in the well (feet)

Explanation: The formula calculates the volume of a cylinder, which is the shape of most wells. The result is in cubic feet.

3. Importance of Water Volume Calculation

Details: Knowing the water volume helps in determining well yield, planning water usage, calculating treatment chemical amounts, and assessing water storage capacity.

4. Using the Calculator

Tips: Measure the well's radius (half of diameter) in feet and the water depth in feet. Enter both values as positive numbers. For best accuracy, measure when the well is at its typical water level.

5. Frequently Asked Questions (FAQ)

Q1: How do I measure the well radius?
A: Measure the diameter across the well opening and divide by 2. If you can't measure directly, consult well construction records.

Q2: How do I determine water depth?
A: Use a weighted measuring tape or electronic depth sounder. Measure from the water surface to the bottom of the well.

Q3: Can I use this for non-cylindrical wells?
A: This calculator assumes a perfect cylinder. For irregular shapes, more complex calculations or direct measurement is needed.

Q4: How do I convert cubic feet to gallons?
A: Multiply cubic feet by 7.48052 to get US gallons. The calculator shows cubic feet as it's the standard unit for such calculations.

Q5: Does this account for well casing thickness?
A: No, you should measure the internal radius (inside of casing) for accurate water volume calculations.
