Distance from Explosion to Exposure given Overpressure Solution

STEP 0: Pre-Calculation Summary

Formula Used

Distance from Explosion to Exposure = ((226.62/Overpressure))^(1/1.407)*(Maximum Weight of Explosives per Delay)^(1/3)
D = ((226.62/P))^(1/1.407)*(W)^(1/3)
This formula uses 3 Variables

Variables Used

Distance from Explosion to Exposure - (Measured in Meter) - Distance from Explosion to Exposure is the space between a hazardous blast and vulnerable entities, measuring potential impact range.
Overpressure - (Measured in Kilopascal) - Overpressure for a charge exploded on the ground surface.
Maximum Weight of Explosives per Delay - (Measured in Kilogram) - Maximum Weight of Explosives per Delay is a single blasting delay to ensure safe and controlled detonation during mining or construction operations.

STEP 1: Convert Input(s) to Base Unit

Overpressure: 20 Kilopascal --> 20 Kilopascal No Conversion Required
Maximum Weight of Explosives per Delay: 62 Kilogram --> 62 Kilogram No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

D = ((226.62/P))^(1/1.407)*(W)^(1/3) --> ((226.62/20))^(1/1.407)*(62)^(1/3)

Evaluating ... ...

D = 22.2211293732136

STEP 3: Convert Result to Output's Unit

22.2211293732136 Meter --> No Conversion Required

FINAL ANSWER

22.2211293732136 ≈ 22.22113 Meter <-- Distance from Explosion to Exposure
