Problem 58832. Find the Peak Particle Velocity on a ETL structure

Created by Andrew Cheyne

PPV is a vibration parameter that can connect stress to a structure, it is measured in mm/s or mm/s-1. The higher the PPV the more stress to the structure. Common practices in power industries are to limit ground motion by specifying the maximum peak particle velocity (PPV). Electrical Tranmission Line (ETL) Structure's maximum PPV without having any damage to the structure is around 50.8mm/s.
There are many different equations for PPV, but all generally have the same variables. 2 site constants and 2 unknowns.
Use this equation to calculate PPV with k & e being the default site constants:
PPV = k(D/sqrt(Q) )^(-e)
k = 185
e = 1.2
D = distance from blast to structure (m)
Q = Charge of mass per delay (kg)

There appears to be an minor mistake in your problem description, or alternatively your test suite: the formula given is

PPV = k(D/sqrt(Q) )^(-e)

and the value of e given is

e = -1.2

but the test suite only wants one minus sign: either it should be (...)^e in the formula instead, or e = 1.2.

Christian, I checked the formula on the internet and corrected the problem statement according to the reference solution submitted by OP.

The value of e is 1.2.
