My son and I have a real problem and we need some help. My son is a licensed blaster. He has been asked to stimulate oil wells with dynamite. I am trying to help him. In short, we will fabricate a "torpedo." Currently, we are thinking of using a 5' length of 1.5" PVC with the down end made into a point. The torpedo will be filled with 2 sticks of dynamite and filled with as dense a sand/gravel as we can find. It will be dropped down a 5" pipe filled with water. It is estimated that it is 640' to the bottom. Can you help me calculate how long it will take the torpedo to reach the bottom? (We need to make sure it gets to the bottom before the fuse ignites the dynamite!!) I am sure the efficiency through the water, drag, is an important and not known for sure variable, but perhaps there is a range that would get us close enough.
Any guidance or leads would be most appreciated. |

Ooooh fluid dynamics. Going to be very tough to estimate given the fact that you're delivering the dynamite in a homemade vehicle with unknown properties. I might think about triggering it via remote control after allowing "more than enough" time for it to reach the bottom. (IMG:style_emoticons/default/idea.gif) Radio Shack is your friend!
