Webresponse, blast wave time of arrival (TOA) is a reliable metric1 which can provide key insights into the behaviour of a blast wave. Since pressure and velocity are … WebAt 50 seconds after the explosion, when the fireball is no longer visible, the blast wave has traveled about 12 miles. It is then traveling at about 784 miles per hour, which is slightly faster than the speed of sound at sea level. Peak overpressure Maximum Wind Speed; 50 psi: 934 mph: 20 psi: 502 mph: 10 psi: 294 mph: 5 psi:
WebNov 12, 2012 · The speed of "sound" is an increasing function of temperature. The wavefront is pushing into undisturbed air, so the excess velocity is not due to the … WebExplosive velocity, also known as detonation velocity or velocity of detonation (VoD), is the velocity at which the shock wave front travels through a detonated explosive. Explosive velocities are always faster than the local speed of sound in the material. If the explosive is confined before detonation, such as in an artillery shell, the force ...
WebJul 9, 2015 · Unlike ordinary sound waves, the speed of a shock wave varies with its amplitude. The speed of a shock wave is always greater than the speed of sound in the fluid and decreases as the amplitude of the wave decreases. When the shock wave speed equals the normal speed, the shock wave dies and is reduced to an ordinary sound … WebAs it expands, the peak pressures of the blast wave diminish and the speed of propagation decreases from the initial supersonic velocity to that of sound in the transmitting medium. However, upon reflection from the earth's surface, the pressure in the wave will be reinforced by the fusion of the incident and the reflected wave (the Mach effect ...
