Overpressure due to Charge Exploded on Ground Surface Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

Overpressure - (Measured in Pascal) - 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.
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.

STEP 1: Convert Input(s) to Base Unit

Maximum Weight of Explosives per Delay: 62 Kilogram --> 62 Kilogram No Conversion Required
Distance from Explosion to Exposure: 5.01 Meter --> 5.01 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P = 226.62*((W)^(1/3)/D)^(1.407) --> 226.62*((62)^(1/3)/5.01)^(1.407)

Evaluating ... ...

P = 162.651569104813

STEP 3: Convert Result to Output's Unit

162.651569104813 Pascal -->0.162651569104813 Kilopascal (Check conversion here)

FINAL ANSWER

0.162651569104813 ≈ 0.162652 Kilopascal <-- Overpressure

What is Overpressure?

Overpressure (or blast overpressure) is the pressure caused by a shock wave over and above normal atmospheric pressure. The shock wave may be caused by sonic boom or by explosion, and the resulting overpressure receives particular attention when measuring the effects of nuclear weapons or thermobaric bombs.
