PV = 6.28 F x D
Where:
PV = Particle velocity, inches per second
F = Vibration frequency, cycles per second
D = Single amplitude displacement of the vibration, inches.

NOTE: Where vibration is produced as discrete impulses, and such impulses
do not exceed frequency of 100 per minute, then the values in Table II may
be multiplied by two.
