1. What is Net Explosive Weight?

Net Explosive Weight (NEW) is the equivalent mass of TNT that would produce an equivalent explosive effect. It's calculated by multiplying the total mass of explosive material by its hazard factor relative to TNT.

2. How Does the Calculator Work?

The calculator uses the NEW equation:

Where:

• Total Explosive Mass — Mass of explosive material in kilograms
• Hazard Factor — Relative effectiveness factor compared to TNT (decimal value)

Explanation: The equation converts different explosive materials to their TNT equivalent for standardized comparison and safety calculations.

3. Importance of NEW Calculation

Details: Accurate NEW calculation is crucial for military operations, demolition planning, safety distance calculations, and storage requirements.

4. Using the Calculator

Tips: Enter total explosive mass in kilograms and hazard factor as a decimal (e.g., 0.75 for 75% as powerful as TNT). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical hazard factor for common explosives?
A: TNT is 1.0 by definition. Other examples: C4 (1.34), ANFO (0.74), RDX (1.60), Dynamite (1.25).

Q2: Why convert to TNT equivalent?
A: Standardization allows comparison between different explosives and simplifies safety calculations.

Q3: How is NEW used in military applications?
A: Used for storage limits, transportation safety, blast radius calculations, and mission planning.

Q4: Are there limitations to NEW calculations?
A: Yes, environmental factors, explosive configuration, and detonation conditions can affect actual blast effects.

Q5: Where can I find hazard factors for specific explosives?
A: Military manuals, explosive manufacturer specifications, or standardized explosive reference tables.
