User blog:Moritzva/A pretty simple calc

As a starting point for Valev's verse, I will use a simple example of when Valev's friend casually destroyed an immense scale of land. The best estimate of the land one could get of this is around 200 meters in radius. So that should be easy.

Let's use 20 PSI as a starting point, since many buildings were destroyed.

W = R^3*((27136*P + 8649)^(1/2)/13568 - 93/13568)^2

W = Tons of TNT

R = Radius in meters (200)

P = Pressure in bars (20 psi = 1.37895 bars)

The yield being a good 642.9144 tons. Multi-City Block level.

Cool.
