Long test-ball exploded 3 feet below, lifting me off ground and threw me 4 feet into embankment. 38lbs psi. Air shock felt 30 feet away. What was the force that has ruined my hearing?? Paul...

You need to know a lot more than what you've given. You probably would need to know what exploded, what gases were produced, the detonating velocity of whatever detonated, how much of it was present, its state of confinement, the tensile strength of whatever confined it, etc.

Hi Perito, A 22" long, 2 5/8" outer diameter rubber tube filled with regular air. Rubber was 3/8" thick. The rubber tube was inserted half its length into a 4" pvc pipe and pumped to 38lbs psi when exploded. Is this enough information Perito? It was a Multi-size multi-stage MS2 Long test ball for testing water pressure. No water was present at time..

Let me do some calculations tomorrow to see if I can figure it out.

Thanks
