Particle Velocity=(5Peak Side-On Pressure7Ambient Pressure)(343.21+6Peak Side-On Pressure7Ambient Pressure)
(c)Speed of Sound
(ps)Peak Side-On Pressure
(po)Ambient Pressure

The Particle Velocity calculates the velocity using the speed of sound, peak on-side pressure and ambient pressure.  This is part of the Rankine-Hugoniot equations.

Note: speed of sound in dry air (343.2 m/s) as the default.  Condition outside of dry air (e.g. underwater) will warrant another value.
