Explosives Quantity Distance Formula:
| From: | To: |
The Explosives Quantity Distance formula calculates the safe distance (D) from an explosive charge based on the weight of explosives (W) and a constant factor (k) that depends on the type of explosive and desired safety level.
The calculator uses the explosives quantity distance formula:
Where:
Explanation: The formula accounts for the cubic root relationship between explosive weight and safe distance, as blast effects scale with the cube root of the explosive mass.
Details: Accurate distance calculation is crucial for establishing safe perimeters around explosive storage areas, determining blast danger zones, and ensuring safety during explosive operations.
Tips: Enter the appropriate k constant for your explosive type and safety requirements, and the weight of explosives in kilograms. Both values must be positive numbers.
Q1: What are typical values for the k constant?
A: k values typically range from 5-20 for different explosives and safety levels. Consult explosive safety manuals for specific values.
Q2: Why is the cube root used in the formula?
A: The cube root relationship accounts for how blast effects scale with explosive mass, as energy release is proportional to mass.
Q3: Does this formula work for all types of explosives?
A: While the basic relationship holds, different explosives may require adjustment factors. Always use manufacturer-recommended constants.
Q4: What safety factors should be considered?
A: Consider terrain, confinement, multiple charges, and whether the calculation is for personnel safety or structural protection.
Q5: Are there regulatory standards for explosive distances?
A: Yes, most countries have specific regulations governing explosive safety distances. Always comply with local regulations.
