After looking online and checking papers I`m not closer to get a useful result. The thing is I find some many different equations and they all give totally different answers.(adsbygoogle = window.adsbygoogle || []).push({});

[a] A wall is 3 m high and infinintly long. An explosion of 25 kg TNT is done at a distance of 10 m on the ground. What is the reflected over pressure Pr and the impulse I of the explosion on the wall? Maybe if someone would know of a could source and I`ll try again

[/a]

2. Relevant equations

Z=R/W^{1/3}

1. P=1772/z_{3}-114/z^{2}+108/Z

2. P=6784(W/R^{3})+93(W/R^{3})^{.5}

1. gives 66.1 bar?

2. gives 184.3 bar?
