Peak Particle Velocity and Scaled Distance
Let:
PPV= Peak Particle Velocity(in/sec)
K and m =Site Specific constants defining initial energy and
decay
Ds=Scaled Distance(ft./Ibs 0.5)
D= Distance to subject structure(ft)
Maximum charge per delay(Ibs)
Given:
D=2406'
Maximum charge=256 Ibs
K= 160
m =-1.6
Scaled Distance:
Ds= D/(✓WMAX)^0.5
Ds=2406/(✓256)AO.5
Ds= 150.375
Peak Particle Velocity
PPV= K(Ds)AM
PPV= 160(150.375)^-1.6
