1. What is the TNT Explosion Calculator?

The TNT Explosion Calculator estimates the blast radius of a TNT explosion based on the amount of TNT and a scaling factor. It's commonly used in safety planning, demolition, and military applications.

2. How Does the Calculator Work?

The calculator uses the cube root scaling law:

Where:

• \( TNT \) — Mass of TNT in kilograms
• \( factor \) — Scaling factor (typically 0.37 for air blast)

Explanation: The cube root scaling law accounts for the three-dimensional nature of explosive energy propagation.

3. Importance of Blast Radius Calculation

Details: Accurate blast radius estimation is crucial for safety planning, determining safe distances, and assessing potential damage from explosions.

4. Using the Calculator

Tips: Enter TNT mass in kilograms and an appropriate scaling factor (default is 0.37 for air blast). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical factor value?
A: For air blast effects, 0.37 is commonly used. Different factors apply for cratering or other specific effects.

Q2: How accurate is this calculation?
A: It provides a rough estimate. Actual blast effects depend on many factors including terrain and atmospheric conditions.

Q3: Can this be used for other explosives?
A: Yes, if you use TNT equivalent weight (actual explosive weight × relative effectiveness factor).

Q4: What does the radius represent?
A: Typically the distance at which significant overpressure or damage occurs, depending on the factor used.

Q5: Are there limitations to this equation?
A: Yes, it doesn't account for height of burst, terrain, or precise damage levels at different distances.
