I have come across the profile for the RPG-7 and it states: "Its theoretical explosive yield from its 10 meter lethal blast radius should be ~95,298,833 J"
I think this is incorrect and I have no idea how it was calculated. Regardless of the fact that 10 meter lethal blast radius is most probably exaggerated, the 50% lethality on human body from blast lung injury at low duration blasts (which occur with low yields) is something around 100-150 psi while the 95,298,833 J (about 25 kg TNT) has 100 psi peak overpressure at 3 meter at best.
So keeping the calculations above aside, could someone explain how 10 meter lethal blast radius corresponds to 25 kg of TNT?
For reference, the below is from The Effects of Nuclear Weapons by Samuel Glasstone and Philip J. Dolan Third Edition:
From observations made with small charges of chemical explosives, it has been estimated that deaths in humans would require sharp-rising effective overpressures as high as 200 to 400 (or more) pounds per square inch when the positive phase durations are less than a millisecond or so. These pressures may be compared with values of roughly 50 (or less) to about 100 pounds per square inch, with positive phase durations of the order of a second, for nuclear explosions.
