29 yr old Orthopaedic Surgeon Grippo from Saint-Paul, spends time with interests including model railways, top property developers in singapore developers in singapore and dolls. Finished a cruise ship experience that included passing by Runic Stones and Church. 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.

Effects of overpressure

According to an article in the journal Toxicological Sciences,

"Blast overpressure (BOP), also known as high energy impulse noise, is a damaging outcome of explosive detonations and firing of weapons. Exposure to BOP shock waves alone results in injury predominantly to the hollow organ systems such as auditory, respiratory, and gastrointestinal systems."

An EOD suit worn by bomb disposal experts can protect against the deadly effects of BOP.

Pressure	Effects
Template:Convert	Reinforced concrete buildings severely damaged Severe heart and lung damage Limbs can be blown off
Template:Convert	Most buildings collapse except concrete buildings Injuries universal Fatalities occur
Template:Convert	Residential structures collapse Brick walls destroyed Injuries common Fatalities may occur

Overpressure calculation (explosive)

Overpressure is determined using "Weibull's formula":

$\mathrm{\Delta }p=2410{\left(\frac{m}{V}\right)}^{0.72}$

where:

• 2410 is a constant based on Template:Convert
• $m$ = net explosive mass calculated using all explosive materials and their relative effectiveness
• $V$ = volume of given area (primarily used to determine volume within an enclosed space)
