Diameter of Borehole Formula:

\[ D_h = \frac{L}{2} \]

Diameter of Borehole (m):

Minimum Diameter (m):

Maximum Diameter (m):

1. What is Diameter of Borehole Calculator?

Definition: This calculator determines the diameter of a borehole based on its length, with optional tolerance percentage.

Purpose: It helps drilling professionals and engineers determine appropriate borehole dimensions for various applications.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ D_h = \frac{L}{2} \]

Where:

\( D_h \) — Diameter of borehole (meters)
\( L \) — Length of borehole (meters)

Explanation: The diameter is calculated as half of the borehole length, with tolerance options to show acceptable variation range.

3. Importance of Borehole Diameter Calculation

Details: Proper borehole sizing ensures structural stability, appropriate material placement, and efficient drilling operations.

4. Using the Calculator

Tips: Enter the borehole length in meters and tolerance percentage (default 5%). The calculator provides base diameter and tolerance range.

5. Frequently Asked Questions (FAQ)

Q1: Why is diameter half of the length?
A: This ratio provides optimal stability for most borehole applications, though specific projects may require different proportions.

Q2: What's a typical tolerance percentage?
A: ±5% is common, but this may vary based on project specifications and material requirements.

Q3: When would I adjust the tolerance?
A: Adjust for precision requirements - tighter tolerances for critical applications, looser for general purposes.

Q4: How do I measure borehole length?
A: Use standard surveying equipment or drilling measurement tools to determine total borehole depth.

Q5: Does this apply to all borehole types?
A: This is a general calculation - specific applications (geotechnical, water wells, etc.) may have different standards.
