Speed of blast wave
WebBlast waves of moderate shock strength emanating from ... The shock speed increases with increasing overpressure. For example, the overpressure corresponding to a shock Mach number of 3 is about 1 MPa. The corresponding shock speed is 1040 mis, which is comparatively high relative to the ambient sound speed (335 mls). ...

View chapter Purchase book Disciplines Involved in Offshore Platform Design Naeim Nouri Samie MSc Hydraulic Structures, in Practical Engineering Management of Offshore Oil and Gas Platforms, 2016 2.9.5 Explosion Overpressure Study WebThe blast wave that is formed as a result of an explosion has some import parameters. One of them is the peak pressure which is basically the pressure measured when the blast wave arrives at a given location. It is the case that this peak pressure decreases as one moves further and further from the center of the explosion.
